How to Crochet a Striped Cardigan: A Complete Step-by-Step Guide

There is something deeply satisfying about wearing a garment you made with your own hands, and a striped cardigan sits at the top of that list. It is cozy, versatile, endlessly customizable, and — once you understand the construction — surprisingly approachable even for intermediate crocheters. Whether you are drawn to bold, contrasting stripes or subtle tonal shifts, this guide will walk you through everything you need to know to crochet a striped cardigan from the very first chain stitch to the finished button band.

Why a Striped Cardigan Is a Great Crochet Project

Before we get into the how, let us talk briefly about the why. A cardigan is one of the most wearable crochet garments you can make. Unlike a pullover, it opens at the front, which means you do not have to wrestle it over your head — and for the maker, that means fewer complicated shaping challenges around the neckline at the beginning of the project.

Stripes add another layer of appeal. They let you use up yarn from your stash, experiment with color without committing to an intricate colorwork pattern, and create a visual rhythm that makes the project feel exciting at every row. They also help you track your progress: when you can see exactly how many stripes you have completed, the work feels less endless.

This tutorial is written for someone who is comfortable with basic crochet stitches — chain, single crochet, half double crochet, and double crochet — and who has made at least a few smaller projects before. That said, every technique is explained clearly, so if you are an adventurous beginner, do not be discouraged.

Materials You Will Need

Getting your materials sorted before you start is one of the best habits you can build as a crocheter. Here is what you will need for a standard adult cardigan.

Yarn: Choose a yarn that has good stitch definition and some elasticity. A smooth DK weight or worsted weight yarn works beautifully for this type of project. Wool blends, cotton blends, and acrylic yarns all produce lovely results. For a classic two-color striped cardigan in a women’s medium, plan for approximately 800–1,000 yards of your main color (MC) and 600–800 yards of your contrast color (CC). Adjust quantities for larger or smaller sizes.

Hook: Match your hook to your yarn’s label recommendation, then adjust based on your gauge swatch. For worsted weight, a 5.0mm or 5.5mm hook is common. For DK, a 4.0mm or 4.5mm hook is typical.

Notions: You will also need a yarn needle for weaving in ends, stitch markers (at least four), a measuring tape, scissors, and the number of buttons you want for the front closure. Typically five to seven buttons work well for a cardigan. Choose buttons that are no wider than 1 inch in diameter.

Optional: A row counter, a blocking mat and pins, and stitch holders or spare yarn for holding live stitches.

Understanding Gauge and Why It Matters

Gauge is the number of stitches and rows that fit within a specific measurement — usually 4 inches by 4 inches. It is the single most important factor in whether your finished cardigan will fit the way you intend.

To check your gauge, crochet a swatch at least 6 inches by 6 inches using your yarn and hook. After crocheting it, lay the swatch flat without stretching it, and count how many stitches and rows fall within a 4-inch square. Compare this to the gauge specified in your pattern.

For a worsted weight project worked in half double crochet, a common gauge is 14 stitches and 10 rows per 4 inches. Your numbers may differ, and that is perfectly fine — just adjust your hook size up or down until your swatch matches. A hook that is too small will give you more stitches per inch (too tight), and a hook that is too large will give you fewer (too loose).

Do not skip the gauge swatch. A garment made at the wrong gauge can end up several sizes too large or too small, no matter how carefully you follow the rest of the instructions.

Choosing Your Stripe Pattern

One of the most enjoyable parts of planning a striped cardigan is deciding on your stripe sequence. There are no rules here — only preferences. A few popular options to consider:

Classic equal stripes alternate between two colors every four to six rows, producing a clean, balanced look that suits almost any style.

Gradient-inspired stripes use three or more colors arranged so that each color transitions gradually into the next. This requires more yarn planning but creates a stunning visual effect.

Bold asymmetrical stripes break the regularity by varying the width of each stripe. You might do twelve rows of your main color, then two rows of contrast, then eight rows of main color again. This approach feels more artistic and modern.

Thin accent stripes within a dominant base color create a subtler look that feels classic and understated. Think two rows of a muted tone every ten rows of a neutral base.

For this tutorial, we will use a simple alternating stripe sequence: six rows in the main color, then six rows in the contrast color, repeating throughout the entire garment. This is easy to track and produces a timeless look.

Cardigan Construction Methods

There are several ways to construct a crochet cardigan, and the method you choose will affect the feel of the finished fabric, the ease of working in stripes, and how much seaming you have to do at the end.

Top-down construction begins at the neckline and works downward, with increases at the raglan points to shape the yoke. The body and sleeves are separated and worked independently after the yoke is complete. This is a very popular method because you can try the garment on as you go and because it minimizes seaming. Stripes work beautifully with this method since you carry your yarn continuously.

Bottom-up construction begins at the hem and works upward. You typically work the back and two front panels separately, then join them and work the yoke as one piece. This method also suits stripes well and gives you excellent control over length.

Seamed construction involves making each piece of the cardigan — back, two fronts, and two sleeves — as flat panels, then sewing them together at the end. This is the most traditional approach and can produce very clean lines, though it requires more finishing work.

For this guide, we will use a top-down raglan construction because it is beginner-friendly, requires minimal seaming, and keeps your stripe sequence consistent across the entire sweater.

Step-by-Step Instructions

Step 1: Measure for Fit

Before you begin, take the following measurements from your body or a well-fitting sweater: bust circumference, shoulder width, upper arm circumference, sleeve length from underarm to wrist, and body length from underarm to desired hem. Write these down and refer to them as you work.

For the sample pattern in this guide, we are working to a women’s medium: 38-inch bust, with 2 inches of positive ease built in for a total worked circumference of 40 inches.

Step 2: Work the Neckline Foundation

Begin with your main color. Chain 60 stitches. This chain forms the neckline of the cardigan.

Row 1: Work one half double crochet (hdc) in the third chain from the hook, then hdc across. You will have 58 stitches.

Row 2 (Yoke Setup Row): Place stitch markers to divide the row into five sections: left front (9 stitches), raglan seam (1 stitch), left sleeve (10 stitches), raglan seam (1 stitch), back (18 stitches), raglan seam (1 stitch), right sleeve (10 stitches), raglan seam (1 stitch), right front (9 stitches). The four single stitches between sections are your raglan stitches and should be marked.

Step 3: Work Raglan Increases

For every right-side row, you will increase two stitches at each raglan marker — one stitch on either side. This means you add 8 stitches every increase row.

To increase: work two hdc into the stitch immediately before the raglan marker stitch, hdc across the raglan stitch, and work two hdc into the first stitch after the marker.

Continue in this manner, working increase rows on every row (or every other row for a slower increase depending on your gauge and the fit you want), until the yoke is deep enough to reach your underarms — typically around 8 to 10 inches from the neckline, or when your sleeve sections are wide enough to match your upper arm measurement.

After completing three rows, switch to your contrast color to begin your stripe sequence. Change colors at the end of a row by pulling the new color through the final two loops of the last stitch of the row. Carry the unused color loosely up the side of the work or cut and rejoin it at each color change — both methods work, though carrying is faster and leaves fewer ends to weave in.

Step 4: Separate Body and Sleeves

When the yoke is complete, it is time to separate the sleeves from the body. On the next row, work across the left front stitches, chain a small underarm bridge (usually 4 to 8 stitches, depending on your arm measurement), skip the sleeve stitches, work across the back, chain another underarm bridge, skip the second sleeve, and work across the right front.

You now have one continuous row of body stitches connected by two underarm chain bridges. Place the sleeve stitches on stitch holders or a length of scrap yarn — you will come back to them.

Step 5: Work the Body

Continue working back and forth across the body stitches, maintaining your stripe sequence, until the cardigan reaches your desired length. For a classic cardigan, this is typically 14 to 16 inches from the underarm. For a cropped version, 8 to 10 inches is a popular choice.

At the hem, you can work one to two inches of single crochet ribbing by turning your work sideways and working into the row ends, or simply finish with a few rows of single crochet for a neat, flat edge.

Step 6: Work the Sleeves

Return to the held sleeve stitches. Reattach your yarn and pick up a few stitches across the underarm chain bridge, joining the sleeve into a round if you prefer working in the round, or continue flat and seam later.

Work the sleeve downward, decreasing occasionally along the sides to taper the sleeve toward the cuff. A common approach is to decrease one stitch on each side every 6 to 8 rows. Continue until the sleeve reaches your desired length, then finish the cuff with an inch or two of single crochet or ribbing.

Repeat for the second sleeve.

Step 7: Work the Button Bands

The button bands run along both front edges of the cardigan and are what give the garment its polished, finished look.

For the button band (usually the left front for women’s cardigans), pick up stitches evenly along the front edge. A good rule of thumb is to pick up one stitch for every row of hdc fabric. Work 4 to 5 rows of single crochet, then fasten off.

For the buttonhole band (usually the right front), work the same way but add evenly spaced buttonholes on the second or third row. To make a simple buttonhole, chain 2 and skip 2 stitches. On the following row, work 2 single crochet into the chain-2 space to close the hole. Space your buttonholes evenly from just above the hem to just below the neckline.

Finishing Your Cardigan

Good finishing is what separates a homemade garment from a handcrafted one.

Weave in all loose ends carefully using a yarn needle, working the tail back and forth through the fabric in different directions so it will not come loose with wear and washing. Trim any excess close to the fabric.

Block your finished cardigan. For natural fibers like wool, wet blocking is ideal: soak the garment in cool water for 15 to 20 minutes, gently press out the excess water without wringing, lay it flat on a blocking mat, pin it to your measurements, and allow it to dry completely. For acrylic yarn, steam blocking or spray blocking can help even out stitches and give the fabric a softer drape.

Once blocked and dry, sew on your buttons opposite the buttonholes. Use a sewing needle and matching thread or a doubled strand of your yarn for this step.

Tips for Working Stripes Cleanly

A few small habits will make your stripe work look noticeably neater.

Always change colors at the end of a row, never in the middle. This keeps the color transitions aligned at one edge of the fabric.

When carrying yarn up the side, wrap the working yarn around the carried strand every two to three rows to keep it snug against the fabric without pulling.

If you want perfectly clean, jog-free stripes on sections worked in the round (like the sleeves), look up the “jogless jog” technique — it involves slipping the first stitch of a new color round and is a small adjustment that makes a big visual difference.

Match your tension at color changes. Some crocheters naturally tighten up when switching colors. Try to keep a relaxed and consistent grip throughout.

Adjusting the Pattern for Different Sizes

To size up or down, the key numbers to adjust are your starting chain and the width of each section in the yoke setup row.

For a smaller size, reduce the starting chain by four to six stitches and scale down each section accordingly. For larger sizes, increase the chain and the stitch counts in each section. Always check that your body section, once separated, will measure the correct circumference when laid flat, and adjust your underarm chain bridges as needed for a comfortable fit.

It is also worth noting that cardigan length is entirely flexible. If you want a long, duster-style cardigan, simply continue working the body section longer. If you want a cropped, boxy style, stop earlier. The instructions for the button bands remain the same regardless of length.

Caring for Your Finished Cardigan

The care your cardigan needs will depend on the fiber content of your yarn. Always check the yarn label for specific washing instructions.

Most acrylic and acrylic-blend cardigans can be machine washed on a gentle cycle and laid flat to dry. Avoid putting hand-knit or hand-crocheted garments in the dryer, as heat can distort the stitches and cause the fabric to felt or shrink.

Wool and wool-blend cardigans are best hand washed in cool water with a gentle wool wash. Support the full weight of the wet garment when lifting it out of the water, as wet wool is heavy and can stretch.

Store your cardigan folded, not hanging, to prevent the shoulders from stretching out over time.

Final Thoughts

Crocheting a striped cardigan is a project that rewards patience and attention to detail, and the result is something you will reach for again and again. The stripe sequence gives you a natural rhythm to the work, the top-down construction means you can try it on as you go, and the finished garment is endlessly wearable across seasons and occasions.

Take your time with the gauge swatch, enjoy the process of watching your stripe sequence grow row by row, and do not rush the finishing steps — they truly do make a difference. Every skein of yarn you choose, every color combination you experiment with, is an expression of your own creativity.

Once you have made one striped cardigan, you will likely find yourself planning the next one before you have even woven in the last end.
