FREE PATTERN + TUTORIAL: Crochet Issa Mesh Cardigan
If you’ve been searching for a crochet cardigan that feels breezy, stylish, and genuinely wearable in real life, this is the one. The Issa Mesh Cardigan is an open-stitch, lightweight layering piece that works up beautifully in a DK or lightweight worsted yarn, and it looks far more complicated than it actually is. Whether you’re a beginner who’s tackled a few projects or an intermediate crocheter looking for your next go-to pattern, the Issa Mesh Cardigan is going to earn a permanent spot in your wardrobe rotation.
In this post, I’m sharing the complete free crochet pattern and step-by-step tutorial so you can make your own from start to finish. I’ll walk you through the materials you need, the stitches used, sizing guidance, and every section of the cardigan in detail. Let’s get into it.
Why You’ll Love This Pattern
The Issa Mesh Cardigan gets its name from the effortless, “issa vibe” energy it brings to any outfit. Throw it over a tank top, pair it with high-waisted jeans, or layer it over a sundress — it just works. The mesh construction means it’s not overly warm, making it perfect for transitional weather, beach cover-ups, or evenings when you need just a little something extra.
From a construction standpoint, this cardigan is worked flat in two main panels that are seamed at the shoulders and sides, with sleeves added afterward. This makes it very beginner-friendly because you’re working in rows rather than complicated in-the-round construction. The mesh stitch itself is a simple combination of chain spaces and single or double crochet stitches that creates that gorgeous open lacework look without requiring you to read complex stitch charts.
Materials You’ll Need
Before you start, gather everything so you’re not hunting around mid-project.
Yarn: Approximately 400–800 yards of DK weight or light worsted yarn, depending on your size. A cotton or cotton-blend yarn is highly recommended for drape and breathability. 100% cotton, linen-cotton blends, or bamboo-cotton blends all work beautifully here. Avoid anything too fluffy or textured, as the mesh stitch definition gets lost in hairy fibers.
Hook: 4.5mm or 5.0mm crochet hook. Start with a 4.5mm and swatch first to check your gauge.
Notions: Yarn needle for weaving in ends and seaming, scissors, stitch markers, measuring tape, and blocking mats and pins if you want a polished finish (highly recommended for cotton yarns).
Gauge: 14 stitches and 8 rows = 4 inches in the mesh stitch pattern. Gauge matters for sizing here, so please swatch before starting.
Sizing Guide
This pattern is written for sizes XS through 3XL with 2–4 inches of positive ease, meaning the finished cardigan will be a bit larger than your actual bust measurement for a relaxed, flowy fit.
XS: 30–32″ bust → finished cardigan measures approximately 34″
S: 34–36″ bust → finished cardigan measures approximately 38″
M: 38–40″ bust → finished cardigan measures approximately 42″
L: 42–44″ bust → finished cardigan measures approximately 46″
XL: 46–48″ bust → finished cardigan measures approximately 50″
2XL: 50–52″ bust → finished cardigan measures approximately 54″
3XL: 54–56″ bust → finished cardigan measures approximately 58″
When in doubt, size up. The open mesh construction means the cardigan will have natural stretch, and the open-front silhouette means exact fit is more forgiving than in a closed sweater.
Abbreviations and Stitch Guide
ch — chain
sl st — slip stitch
sc — single crochet
dc — double crochet
ch-sp — chain space
sk — skip
rep — repeat
RS — right side
WS — wrong side
st(s) — stitch(es)
Mesh Stitch (used throughout this pattern):
Row 1 (RS): Ch 4 (counts as dc + ch 1), sk 1 st, dc in next st, ch 1, sk 1 st, dc in next st; rep from across, turn.
Row 2: Ch 4 (counts as dc + ch 1), dc in first ch-sp, ch 1, dc in next ch-sp; rep from across, ending dc in 3rd ch of turning ch, turn.
Repeat Row 2 for pattern.
This creates the classic mesh grid that defines this cardigan’s aesthetic.
Pattern Notes
Read through the entire pattern before starting. The cardigan is worked in four pieces: a back panel, two front panels (left and right), and two sleeves. Everything is seamed together using a slip stitch or mattress stitch seam, whichever you prefer. A simple edging is added at the end around the neckline, front openings, and hem.
If you’re new to mesh stitches, I want to reassure you: working into the chain spaces rather than into individual stitches feels a little strange at first, but you’ll find your rhythm within the first few rows. The key is consistency — always count your ch-spaces to make sure you haven’t accidentally gained or lost any.
The Pattern
Back Panel
For Size S (adjust stitch count for other sizes per the chart below):
Foundation chain: Ch 68.
Row 1 (RS): Dc in 6th ch from hook (counts as first dc + ch 1 + sk 1), ch 1, sk 1 ch, dc in next ch; rep from across — you should have 32 dc and 31 ch-1 spaces. Turn.
Row 2: Ch 4 (counts as dc + ch 1), dc in first ch-sp, ch 1, dc in next ch-sp; rep from across, ending with dc in 3rd ch of turning ch. Turn.
Repeat Row 2 until the back panel measures 14 inches from the foundation chain (or your desired body length). This is your body length before the armhole shaping begins.
Armhole Shaping:
Sl st across the first 3 ch-sps, ch 4, continue in mesh pattern across, leaving the last 3 ch-sps unworked. Turn. You’ve now decreased 3 mesh units on each side.
Continue in mesh pattern without further shaping until the armhole measures 8 inches (for size S) or your desired depth.
Fasten off and weave in ends.
Foundation chain counts by size:
XS: Ch 60 / S: Ch 68 / M: Ch 76 / L: Ch 84 / XL: Ch 92 / 2XL: Ch 100 / 3XL: Ch 108
Each size increases by 8 chains, which adds 4 mesh units (2 inches) to the width. Armhole shaping removes 3 ch-sps on each side for all sizes.
Front Panels (Make Two, Mirrored)
Each front panel is half the width of the back panel, plus 1 mesh unit for overlap at center front.
For Size S:
Foundation chain: Ch 36.
Work rows 1–2 exactly as for the back panel, then repeat Row 2 until the piece matches the back body length (14 inches).
Armhole Shaping (for the side edge):
On the next row, sl st across the first 3 ch-sps (this is the side seam edge), then continue in mesh pattern to end. Turn. Continue even until armhole depth matches back panel.
Neckline Shaping:
Once the armhole reaches the correct depth, you’ll begin shaping the neckline on the inner (center front) edge.
Work in pattern across to the last 4 ch-sps. Turn, leaving those 4 ch-sps unworked. This shapes the shoulder neckline softly without requiring complex decreases.
Continue in pattern on remaining stitches for 2 more rows, then fasten off.
Repeat for the second front panel, working the armhole shaping and neckline shaping on the mirrored edges.
Foundation chain counts for front panels:
XS: Ch 32 / S: Ch 36 / M: Ch 40 / L: Ch 44 / XL: Ch 48 / 2XL: Ch 52 / 3XL: Ch 56
Sleeves (Make Two)
The sleeves are worked flat and seamed, then set into the armhole. They have a gentle taper from a wider upper arm down to a slightly narrower cuff.
For Size S:
Foundation chain: Ch 52.
Row 1: Work in mesh pattern across — you’ll have 24 ch-sps.
Work even in mesh pattern for 4 rows.
Sleeve Taper:
Row 5: Sl st across first ch-sp, ch 4, continue in pattern to last ch-sp, leave last ch-sp unworked. Turn.
Repeat this decrease row every 6 rows, 3 more times total, until you have 17–18 ch-sps remaining.
Continue even until sleeve measures 18 inches from foundation chain (or your desired length for a full-length sleeve). For a 3/4 sleeve, stop at 13 inches.
Fasten off and weave in ends.
Foundation chain counts for sleeves by size:
XS: Ch 44 / S: Ch 52 / M: Ch 56 / L: Ch 60 / XL: Ch 64 / 2XL: Ch 68 / 3XL: Ch 72
Assembly
Once all four pieces are complete, lay them out on a flat surface and check that the panels are the correct size before seaming. Blocking your pieces before assembly makes everything easier and gives you a much cleaner finished cardigan.
Blocking: Soak your pieces in cool water for 15–20 minutes, squeeze out gently (do not wring), then lay flat on blocking mats, pin to measurements, and allow to dry completely. For cotton, this can take 12–24 hours.
Shoulder Seams: Hold the back panel and one front panel with right sides together. Using your yarn needle and a length of yarn, seam the shoulder edges together using mattress stitch or whip stitch, working across approximately 8–10 ch-sps from the outer edge in (leaving the center open for the neckline). Repeat on the other side.
Side Seams: Fold the cardigan so front and back panels align at the sides. Seam from the hem up to the start of the armhole shaping on each side.
Setting in the Sleeves: Fold each sleeve in half lengthwise to find the center top, and use a stitch marker to mark it. Match this center point to the shoulder seam, then pin the sleeve into the armhole opening, distributing evenly. Seam around the armhole. Seam the sleeve underarm seam from cuff to underarm.
Edging
A simple edging pulls the whole cardigan together and gives it a polished, finished look.
Body Edging:
Starting at any point along the bottom hem, join yarn with a sl st. Work a row of sc evenly around the entire outer edge of the cardigan — along the hem, up the right front opening, around the back neckline, down the left front opening, and back along the hem. Work 3 sc in each corner to keep the edges flat.
For an extra decorative touch, work a second row: ch 3, sk 1 sc, sl st in next sc; rep from around. This creates a simple picot edging that echoes the mesh body without overwhelming it.
Cuff Edging:
Work 1 row of sc around each cuff opening, then the same optional picot row if desired.
Fasten off all ends and weave in securely.
Tips for Success
Count your mesh spaces at the end of every row. Mesh patterns are very easy to accidentally gain or lose a stitch in, and catching it immediately saves you from ripping out many rows later.
Use a stitch marker on Row 1. Place a marker in the first ch-sp of every odd-numbered row until you feel confident in the stitch pattern.
Don’t skip blocking. I know it takes patience, but blocking a cotton mesh cardigan is transformative. Stitches even out, the drape improves dramatically, and your seams lie flat. It’s the difference between a handmade-looking piece and a professional-looking one.
Tension consistency matters more than exact gauge. If your tension shifts between tight and loose throughout the project, you’ll end up with wavy edges. Try to work at the same time of day, in the same position, and take breaks if your hands are tired.
When in doubt, go up a hook size. Mesh stitches tend to look better with a little more drape than density. If your swatch looks stiff or fabric-like rather than open and airy, try the next hook size up.
Yarn Substitution Ideas
If you want to try different yarns, here are some that work beautifully with this pattern.
For a crisp, structured look, try a 100% mercerized cotton in a lighter colorway — white, cream, sage, or dusty blue are stunning for the mesh. For more drape, a Tencel or bamboo-blend yarn will give you an almost silky finish. If you want a slightly cozier version for fall, a cotton-acrylic blend in a heavier DK weight will add just enough warmth without losing the open feel of the mesh.
Avoid super bulky yarns for this specific pattern — the mesh structure works best at lighter weights where the open spaces remain delicate and defined. If you love a thicker yarn, I’d recommend checking the gauge carefully and adjusting your hook and stitch count accordingly.
Ways to Style the Issa Mesh Cardigan
This piece is incredibly versatile. Here are a few outfit combinations to get you inspired before you’ve even finished hooking.
Pair it with a fitted crop top, high-waisted wide-leg trousers, and sandals for a casual chic daytime look. Layer it over a ribbed bralette or bandeau for a more fashion-forward aesthetic. Throw it on over a swimsuit as a beach cover-up — the mesh is literally perfect for this, and the open structure dries quickly. For a cozy fall version made in a cotton-acrylic blend, wear it over a long-sleeved turtleneck with jeans and boots.
The open-front design means you can also belt it at the waist with a thin sash or rope belt to create a more defined silhouette if you prefer that over the relaxed open drape.
Final Thoughts
The Issa Mesh Cardigan is one of those patterns that rewards you every step of the way. The mesh stitch is repetitive enough to be meditative once you’ve got your rhythm, but visually interesting enough to keep you engaged. And when you’re done, you have a genuinely beautiful, wearable piece that will get compliments every time you wear it.
