Blue Star Baby Blanket Free Crochet Pattern
Introduction
This Blue Star Baby Blanket is a sweet, modern heirloom that even a first-time crocheter can finish with confidence. It's made from 49 solid granny squares in alternating white and blue, each one centered with a little white star appliqué, then joined in a simple 7x7 grid. The result is a soft, flat, 30-inch square blanket with a crisp checkerboard look and a cozy, dense fabric that's perfect for tummy time or snuggling. Because every square is the same easy four-round repeat, you'll have the pattern memorized before you know it, and the star appliqués add just enough charm to make it a treasured baby shower gift.

Gauge
One finished granny square measures 4 inches (10 cm) after blocking. Work one square and block it lightly to check — if it's larger, go down a hook size; if smaller, go up.
Tips Before You Start
- Make all 49 squares first, then block them to 4 inches before joining so your grid lines up evenly.
- Keep your tension relaxed and consistent — solid granny squares can pull tight at the corners if you crochet firmly.
- Count your stitches at the end of each round; the totals below are your checkpoints.
- Weave in square ends as you go so the finishing stage stays quick and tidy.

Assembly
Arrange the 49 squares in a 7x7 grid, alternating A and B squares in a checkerboard. With right sides facing, whipstitch squares together using A, working through back loops only.
Sew one star appliqué to the center of each square using A and the 6-inch tail.
Edging
Setup: With A, join yarn at any corner of the assembled blanket.
R1: Ch 1, sc evenly around entire blanket, working 3 sc in each corner; join with sl st to first sc.
R2: Ch 1, sc in each sc around, working 3 sc in each corner; join with sl st to first sc.
Fasten off.
Assembly and Finishing
Whipstitch all squares through back loops only with right sides facing so the seams sit neatly on the back. Sew each star centered on its square, using the tail and a few secure stitches at each point. Weave in all ends on the wrong side. Block the finished blanket to 30 x 30 inches (76 x 76 cm) by misting lightly and pinning flat, then let it dry completely before gifting.
Pro Tips and Variations
- Swap blue for pink, mint, or gray for a different nursery palette — the yardage stays the same.
- Use a contrasting color for the star appliqués, or add a small sc border around each star for extra definition.
- For a larger blanket, add rows of squares in multiples of 7 and increase yarn accordingly.
