About This Building Blocks Crochet Cardigan Pattern
This pattern creates a warm, textured Building Blocks Crochet Cardigan worked in single crochet with chain-1 spaces for an easy, reversible fabric.

Its made with Bernat Forever Fleece Tweeds for a soft, tweedy finish that looks polished with minimal effort.

Why You'll Love This Building Blocks Crochet Cardigan Pattern
I absolutely love this pattern because it transforms bulky yarn into a sophisticated, wearable cardigan with minimal stitches. I enjoy how the simple sc/ch-1 motif creates a plush, reversible texture that looks far more complex than it is. I also appreciate that it is written for a wide range of sizes, so you can make it for yourself or as a thoughtful gift. The finishing steps are straightforward and rewarding, giving you a polished garment at the end of your work.
Switch Things Up
I love customizing this cardigan by changing yarn color and texture; try a solid bulky yarn for a cleaner look or a variegated tweed for extra visual interest.
I sometimes lengthen the body by repeating more Sc/Ch-1 pat rows until Ive added a few extra inches to suit my height.
I will adjust sleeve length by making the sleeve measurement shorter or longer depending on whether I want cuffed or full-length sleeves.
I also like to add patch pockets by crocheting small rectangles in the same pat and sewing them to the fronts for functionality and style.
For a more fitted shape, I decrease a few sts along the side seams before seaming to taper at the waist.
I occasionally add buttons or a single large toggle to the front for closure; add buttonholes by skipping a ch-1 sp when working the front edge rows.
If I want a chunkier collar, I extend the neck extension rows or fold the collar over and stitch in place for extra bulk.
I recommend trying different hook sizes to change drape—bigger hooks give a more open, slouchy cardigan while slightly smaller hooks make a denser, more structured fabric.
I like to experiment with contrasting cuffs or collar by working a few rows in a different color for a subtle trim effect.
For a summery version, I use a lighter weight yarn and smaller hook, then reduce the number of rows to keep the cardigan lightweight and breathable.
I also enjoy making matching sets by crocheting a beanie or scarf in the same Sc/Ch-1 pattern to coordinate with the cardigan.
Common Mistakes & How to Fix Them
✗ Skipping the ch-1 spaces and working into the chain will distort the reversible texture; insert your hook into the space created under the ch-1 and work single crochet there.
✗ Not counting sc and ch-1 spaces as stitches can make pieces too wide or narrow; always count sc and ch-1 spaces as sts and check stitch counts after each row.
✗ Failing to place shoulder markers will make seaming imprecise and misaligned shoulders; place markers 16 (20-22-24-26) sts in from each side for accurate shoulder placement.
✗ Cutting yarn too short for seams causes difficulty during finishing; leave a 16" (40.5 cm) tail at the end of body and sleeve pieces to sew seams comfortably.
