Learn how to crochet the Sera Cardigan. This free crochet cardigan pattern includes 9 women’s sizes. This cardigan is easy to crochet and even easier to wear.
The Sera Cardigan is a lightweight and easy to layer sweater. Featuring a classic fit this crochet cardigan is comfortable for around the house or a day out. It’s perfect for an evening walk, or passeggiata serale.
Made with double crochets, the stitch pattern is simple and easy to remember. I wanted minimal seaming on this design, but all the customizing ability. You can easily adjust length of the sweater or the sleeves. And there are only seams on the shoulders and armholes!

The subtle v-neck shaping give this easy cardigan a great fit. I love how simple it is to decrease in some crochet stitches. Here it’s just a matter of making one less double crochet.

I find this length the most versatile for my wardrobe. But, of course adjusting the length of your cardigan is easy, with a little planning. Look for more details in the free crochet pattern below.

I’ve had this Vanna’s Style yarn in my stash for a while, I knew I wanted to create a spring cardigan with it. The texture and sheen pairs so well with the stitch.
Unfortunately it’s discontinued, although you can still find it in some places. It’s a #3 lightweight/dk yarn, but I found it to be a thicker #3 yarn. When I need to sub out yarn I almost always check YarnSub.com for comparable.
If you only have #4 medium worsted weight yarn, I think that could easily work for this pattern. However, you’ll need to meet gauge with your chosen yarn/hook. Otherwise, your cardigan might not fit!

Materials
- #3 lightweight yarn, pictured is Vanna’s Style Yarn in Olive yds by size: (XS) 1000 (S) 1100 (M) 1225 (L) 1300 (XL) 1450 (2X) 1600 (3X) 1700 (4X) 1800 (5X) 1950
- 5mm hook, pictured below is my Furls Odyssey in Peach, stitch markers, yarn needle, measuring tape, scissors

Notes
- Please read through all notes and pattern before you begin.
- Work up a gauge swatch using the provided gauge information. Measure your swatch and if your gauge matches, great continue on; if not, change your hook size and swatch again. Are your stitches are smaller? Then go up a hook size, and if they’re larger, go down a hook size.
- Ch 3 counts as a stitch, I highly recommend using a ch 3 alternative, here’s my favorite.
- St multiple is 2 + 6.
- Check stitch count before starting a new section.
- Pattern is written for multiple sizes, with the smallest size written first and each subsequent size written in parentheses XS (S, M, L, XL, 2X, 3X, 4X, 5X). For example: Row 1. FDC 104 (120, 136, 144, 160, 176, 184, 200, 208). To make an XS you would foundation double crochet 104, for a M you would foundation double crochet 136 and a 4X you would foundation double crochet 200.

Construction
The main body is crocheted as one piece, bottom up. We will then separate the cardigan into three pieces, creating armholes for the sleeves, while also creating the front and back panels. These are seamed together at the shoulder. The sleeves are worked separately, from the wrist up and in the round, but turned to keep the stitch pattern the same. The sleeves are seamed on at the armholes.
Fit/Adjustment
Pattern adds 2-4” of ease to bust measurement, for a classic fit. For a looser fit, go up a size, for a snugger fit, go down a size. To adjust length of cardigan add or subtract rows before dividing. Measure from your underarm to where you want the cardigan to stop. This is your desired length before dividing.

Pattern
XS (S, M, L, XL, 2X, 3X, 4X, 5X)
Row 1. FDC 104 (120, 136, 144, 160, 176, 184, 200, 208) or if you’re unfamiliar with FDC you can CH 106 (122, 138, 146, 162, 178, 186, 202, 210), dc in the 4th ch and in each ch across, turn.
Row 2. Ch 3, dc in next st and in each st across, turn.
Row 3. Rep Row 2. Now is a good time to check your “actual bust”: 32 (36.9, 41.9, 44.2, 49.2, 54.2, 56.7, 61.6, 64)”
Row 4. Ch 3, dc in next 2 sts, *{sk next st, 2 dc in next st} rep from * til 3 sts left, dc in last 3 sts, turn. (104,120, 136, 144, 160, 176, 184, 200, 208) sts
Rows 5-31. Rep Row 4. If you would like a longer cardigan add more rows here, end on an odd row. *We will add 6 (7, 7.5, 8, 8, 9, 9, 10, 10)” to the length once panels are divided.
Divide
*Check stitch count before dividing.
Now we’ll divide the front right (when wearing), back, and left front (when wearing) panels. Count off (26, 30, 34, 36, 40, 44, 46, 50, 52 sts) and place 1st st marker in next st. First (26, 30, 34, 36, 40, 44, 46, 50, 52 sts) are the Front Right Panel. 1st st marker begins the back panel. Begin with the marked st and count (52, 60, 68, 72, 80, 88, 92, 100, 104 sts) place 2nd st marker in the last st counted. This marks the end of the Back Panel. The remaining (26, 30, 34, 36, 40, 44, 46, 50, 52 sts) are the Front Left Panel (when wearing). *Note the marked sts are a part of the Back Panel st count.
Finished panels will look like the picture:

Seam
Turn cardigan WS out so RS are touching. Line up shoulders to back panel. Use the mattress stitch to sew shoulders to back panel. Cut yarn. Now is a good time to try it on and make any adjustments.
Sleeves
Make 2
-Join and turn each round.
-Sleeves are worked from the wrist up, so you can try them on at anytime and add or subtract increases as needed.
-We will increase on either side of the join, at this point the stitch pattern will look a little different, but this will be our faux seam so it will be on the underside.
-Sleeves XS-3X are written for 18.5” and 4X-5X for 19” in length.
-To adjust your sleeve length: try on your sleeveless cardigan, measure from the shoulder edge down to your hand-or where you want your sleeves to end. This is your desired sleeve length. You can add or subtract rounds according to your need.
