“Iris Stitch” Baby Blanket Crochet Pattern Free
If you’re looking for a soft, airy, and totally beginner friendly blanket pattern, the Iris Stitch is it. This stitch gives off a lacy texture that looks fancy but is seriously easy to crochet. I’m sharing a free baby blanket crochet pattern below, plus instructions to make it in any size you want.

Why You’ll Love the Free Baby Blanket Crochet Pattern
Most of my classic baby blanket patterns have rows of SC stitch or DC stitches. Very basic and sometimes boring if you make the pattern over and over again. This blanket uses the beautiful Iris Stitch in a one row repeat to create beautiful texture and still uses those two main crochet stitches. The Iris Stitch has a light, open feel that works perfectly for baby blankets, spring throws or even bed size afghans.
Pattern Details
Skill Level: Easy
Stitch Used: Iris Stitch (made with 2DC, CH1, 2DC in same stitch)
Hook Size: H/8 (5.0 mm)
Yarn: Any medium weight (worsted #4) yarn
Sample Size: 34.5″ x 41″ baby blanket (crib blanket)

Gauge
Approx. 4 Iris stitch repeats = 4 inches
(But don’t stress about it, this pattern is flexible and can easily be adjusted by chaining more or fewer stitches.)
Additional Notes
- Repeat row 2 until done.
- Each “Iris” is made of (2 dc, ch 1, 2 dc) in the same stitch or space.
- Always work each Iris into the ch-1 space from the previous row, not between stitches.
- You can make the blanket wider or narrower by chaining in multiples of 4 + 3.

How to Adjust to Any Blanket Size
The best part about this pattern is how easily you can resize it. Here’s the secret: just chain in multiples of 4, then add 3 extra chains. I always make the length of my blankets slightly larger than the width of the blankets. The foundation row is your width. So make that starting chain whatever width you want in multiples of 4 and then add 3 at the end. Keep crocheting rows until the blanket measures the length you want. That’s it!
