This lace jacket sweater pattern is designed for a full size range from XS to XXL, making it accessible and adaptable for every body.
Whether you are a confident intermediate knitter looking to add something beautiful to your project queue, or an advanced beginner who has outgrown beginner scarves and dishcloths and is ready to tackle a full wearable garment, this guide will walk you through everything you need to know — from materials and gauge to construction method, stitch breakdown, and finishing tips. By the end, you will have everything you need to download this PDF knitting pattern and cast on with confidence.
Why a Raglan Construction?
Before we dive into the lace details and the specifics of this cardigan pattern, it is worth talking about why raglan construction is such a beloved choice for knitters at all skill levels.
A raglan sweater is worked so that the sleeves and the body of the garment join at a diagonal seam running from the underarm up to the neckline, rather than meeting at a straight horizontal shoulder seam. This creates a natural, sloping shoulder line that fits a wide variety of body shapes comfortably and forgivingly. Because of the way the shaping is worked gradually across multiple rows, raglans are also far more beginner-friendly than set-in sleeve constructions — you are not dropped down into a pit of short rows and complicated sleeve cap math.
For a button-up cardigan like this lace jacket sweater, the raglan method offers another major advantage: the garment can be worked top-down in one piece, meaning you begin at the neckline, work the raglan increases outward to create the yoke, and then separate the body and sleeves to continue each section individually. The result is a sweater with minimal seaming and a smooth, continuous fabric that drapes beautifully. If you prefer a bottom-up construction, the pattern includes notes for working that direction as well, but the top-down method is the recommended approach for most knitters.
What Makes This a Lace Jacket Sweater?
The term “lace jacket sweater” might sound intimidating, but the lace in this design is thoughtfully placed and worked in a way that is achievable for anyone who has mastered a basic yarn-over and a decrease. The lace panels run along the front button bands and down the sleeves, adding a delicate, feminine touch without overwhelming the rest of the fabric. The body of the cardigan is worked in a simple stockinette or reverse stockinette depending on your preference, letting the lace sections stand out as a beautiful contrast.
The lace pattern used in this design is a classic eyelet chevron motif — a repeated sequence that creates small V-shapes and elongated openings in the fabric. It is rhythmic and meditative once you have worked through the first repeat, making it one of those patterns where you find yourself looking forward to the lace sections rather than dreading them. The motif is a 6-stitch, 8-row repeat, which means it is easy to memorize and easy to place back on track if you lose your place.
For those who prefer a completely solid fabric, the pattern notes include a stockinette substitution so you can work the entire cardigan without any lace. The silhouette and construction remain the same — only the texture changes.
Materials You Will Need
To complete this raglan cardigan knit pattern, gather the following before you begin. Having everything on hand before casting on will save you frustration mid-project.
Yarn: This pattern is designed for a DK or light worsted weight yarn (also labeled as 3 or 4 on the weight scale). A yarn with some natural fiber content — merino wool, alpaca, a wool-cotton blend — will give you the best stitch definition for the lace sections and the most comfortable finished fabric. For a cardigan this size across the full range, you will need approximately 800 to 1,500 yards depending on your size. Smaller sizes will fall closer to 800, while an XXL will require closer to 1,400–1,500 yards. Always purchase an extra skein as insurance.
Needles: US size 6 (4mm) circular needles, 32 inches or longer, for the body and yoke. You will also want a second set of the same size or one size smaller for the button band. A set of double-pointed needles or a short circular needle in the same size for the sleeves, if you do not use the magic loop method.
Notions: Stitch markers (at least 6), a tapestry needle for weaving in ends, removable locking stitch markers, a cable needle (optional, for the lace if you prefer to have one handy), and five to seven buttons depending on your preferred button spacing. Buttons that are approximately ¾ to 1 inch in diameter work best for this design. Horn buttons, wooden buttons, and mother-of-pearl buttons all look stunning with this cardigan.
Gauge: 22 stitches and 30 rows = 4 inches in stockinette stitch after blocking. Gauge is not optional in garment knitting — please swatch, and please wash and block your swatch before measuring it. A swatch that has not been wet and dried flat will not accurately represent your finished fabric, and even a half-stitch difference over 4 inches will translate to several inches of difference in a finished sweater.
Understanding the Size Range: XS Through XXL
One of the most important features of this pattern is the complete size inclusivity. The pattern is graded across six sizes: XS, S, M, L, XL, and XXL, with finished bust measurements ranging from approximately 34 inches (XS) up to 54 inches (XXL). The pattern is written with 2 to 4 inches of positive ease built in, meaning the finished garment is intended to be slightly larger than your actual body measurement for a relaxed, comfortable fit.
To find your size, measure your bust at the fullest point and add your desired ease. If you measure 38 inches and prefer a closer fit, choose the size with a finished measurement around 40–41 inches. If you prefer a drapier, more oversized silhouette, choose a finished measurement 4–6 inches larger than your actual measurement.
The pattern is written with all sizes included simultaneously, following the widely used convention of listing the smallest size first and additional sizes in parentheses — XS(S, M, L, XL, XXL). Highlighting your size before you begin knitting will prevent the common mistake of following the wrong number mid-pattern.
Construction Overview: How This Cardigan Is Worked
Understanding the big picture of a pattern before you begin is one of the best habits you can build as a knitter. Here is the full construction flow of this lace jacket sweater.
The cardigan begins with a provisional cast-on or a long-tail cast-on at the back neck. From the neckline, you will work a short section of back neck shaping using short rows to give the back of the collar a slight lift, which dramatically improves how the neckline sits on the body. After the short row section, you will join for working the yoke flat (since this is an open-front cardigan with button bands, the piece is worked flat throughout rather than in the round).
The yoke is where the magic happens. Four raglan markers divide your stitches into sections — the left front, the left sleeve, the back, and the right sleeve, and the right front. On every right-side row, you will work a paired increase at each of the four raglan markers, adding 8 stitches per right-side row. This gradual expansion is what creates the diagonal raglan lines that characterize this style of sweater. You will continue the raglan increases until the yoke reaches the underarm depth appropriate for your size.
At the underarm separation, the sleeve stitches are placed on hold (on scrap yarn or a stitch holder), and a small number of underarm stitches are cast on at each side to bridge the gap. The body continues downward in one flat piece — both fronts and the back together — until you reach your desired length. Hem shaping can be worked straight across for a classic boxy hem or slightly curved for a shaped hem, and the pattern provides instructions for both options.
The sleeves are then picked up and worked in the round from the held stitches. They taper gently toward the cuff using evenly spaced decreases, and end with a small section of ribbing or lace cuff depending on your preference.
The button band is worked last, picked up around the entire front opening and neckline as one long continuous band. Buttonholes are worked on one side during this process, evenly spaced according to the size of your buttons and the length of your front opening.
The Lace Pattern: Row by Row
Here is the lace motif used in the sleeve and front band accent panels. This is written for a flat panel of 13 stitches, including one selvage stitch on each side.
Row 1 (RS): Sl1, k1, yo, ssk, k1, k2tog, yo, k1 repeat to last 2 sts, k2.
Row 2 (WS): Sl1, purl to last stitch, k1.
Row 3 (RS): Sl1, k2, yo, ssk, k1, k2tog, yo, k1 repeat to last 3 sts, k3.
Row 4 (WS): Sl1, purl to last stitch, k1.
Row 5 (RS): Sl1, k1, k2tog, yo, k1, yo, ssk, k1 repeat to last 2 sts, k2.
Row 6 (WS): Sl1, purl to last stitch, k1.
Row 7 (RS): Sl1, k2, k2tog, yo, k1, yo, ssk, k1 repeat to last 3 sts, k3.
Row 8 (WS): Sl1, purl to last stitch, k1.
Repeat rows 1 through 8 for the pattern. As you work through the first two repeats, you will begin to see the chevron eyelet motif emerge clearly in the fabric. The pattern is easy to read once you can see it developing in front of you.
Tips for Knitting Success
Knitting a cardigan is a significant commitment of time and yarn, and a few good habits will protect your investment.
Swatch in your actual stitch pattern, not just stockinette. Lace fabric often behaves differently from plain fabric, and your gauge may shift when you switch between the two sections of this cardigan. Measuring your gauge in both will give you a complete picture.
Block your swatches and your finished garment. Lace especially relies on blocking to open up and show its full beauty. A lace panel that looks muddy and compressed on the needles will transform into something delicate and defined after a gentle soak and a careful pin-out. This is not an optional step for this design.
Keep a row counter going at all times during the lace sections. Even experienced knitters lose track of where they are in an 8-row repeat when life interrupts. A simple tally mark system on paper works perfectly well.
When working the raglan increases, use a consistent method throughout the garment. The pattern recommends M1L (make one left) and M1R (make one right) increases for a tidy, directional result that follows the raglan line cleanly. Inconsistent increases in this area create a messy diagonal line that is noticeable in the finished garment.
Join new skeins at the beginning of a right-side row whenever possible, and leave tails of at least 6 inches for weaving in. Tails woven in at the side edge of a flat piece are more secure and easier to hide than tails woven in mid-row.
Finishing: The Details That Make the Difference
A beautifully knitted body can be let down by rushed finishing, and a careful finishing job can elevate even an imperfect fabric. Here are the key finishing steps for this lace jacket sweater.
After blocking the body flat, join the underarm seams using Kitchener stitch if you have left live stitches, or mattress stitch for seaming. Mattress stitch creates an almost invisible join on the right side of stockinette fabric and is worth learning if you have not already.
Sew buttons on the opposite side from the buttonholes, aligning them carefully. Place a pin through each buttonhole to mark the button placement before sewing — this small step takes 60 seconds and prevents the frustration of buttons that do not align.
Weave in all ends on the wrong side of the fabric, working the tail in two directions (first one way along the edge of the stitches, then back the other way) for maximum security. Trim ends to about ¼ inch after weaving.
If the button band is rolling or the edges of the lace panels are curling, a light blocking spray and a careful pinning of the edges will solve the problem. Cotton and plant-based fibers benefit most from wet blocking, while wool can be wet blocked or steam blocked depending on your preference.

Why Knitters Love This Pattern
A raglan construction paired with lace detailing and a full size range is a combination that tends to generate a lot of finished objects — and a lot of enthusiasm in the knitting community. This is the kind of pattern that works just as well in a soft charcoal grey as it does in a warm blush pink or a deep forest green. The silhouette is timeless enough to wear for years, and the lace accents give it just enough visual interest to feel special without being fussy.
Knitters who have worked through the pattern frequently report that the yoke portion is satisfying because of how quickly the stitch count grows — each right-side row is adding 8 stitches, and you can see the sweater taking shape within the first two or three inches of working. The lace sections, once memorized, become genuinely relaxing. And the button band pickup, which sounds intimidating to many first-time garment knitters, is walked through step by step in the pattern notes so that it feels completely manageable.
This is a garment you will wear. Not one that will sit finished in a drawer because it does not quite fit or does not quite look like you imagined — but one that you will reach for on cool mornings, layer over a dress, button up for a walk, and feel proud of every single time someone asks where you got it.
Cast on with confidence. Your lace jacket sweater is waiting.
