Crochet Rainbow Baby Blanket FREE Pattern

Hi Makers! I have a lovely crochet rainbow baby blanket pattern to share with you today. My favorite thing about this design is not only the rainbow stripes (because who doesn’t love a gorgeous rainbow?!?), but is actually the texture. It’s equally beautiful on both sides!

Rainbow Isles Crochet Baby Blanket Pattern

ch 132 with Hot Pink

Row 1: sc in the 3rd ch from hook, sc in each st across, ch 2, turn. Maker Tip: See Photos A and B

Photo A – Use a stitch marker to mark the last chain made in the foundation chain. This will make it easier to identify and stitch into when working the next row.
Photo B – Use a stitch marker to mark the second chain in each row that ends with a chain 2. The white arrows are pointing to chains 1 & 2 of the turning chain. The black arrow is pointing to the stitch that you will work into when you begin row 2 (same st as the ch-2).

Row 2: MC across starting in same st as the ch-2, do not chain 1 to close the cluster at the end of the row, instead you will DC in the same st; ch 1, turn. See Photos B, C, D and E. 

Photo C – Skip the stitch that the black arrow is pointing to. Finish working the mixed cluster stitch in the stitch marked with the white arrow.
Photo D – Completed mixed cluster stitch. The white arrow in this picture indicates where you will insert your hook when working the next mixed cluster stitch.
Photo E – Last stitch in mixed cluster row. Note there is not a ch to close the cluster, but instead there is a DC worked into the same stitch as the last mixed cluster.

Row 3: (ch-1 counts as a st) sc in each st across, ch 2, turn.  See Photo F.

Photo F – The black arrow in this picture indicates the ch 1. The white arrow indicates the first stitch in this row. Since the chain 1 counts as a stitch you will not begin this row in this first stitch. You will begin working the single crochets in this row in the stitch indicated with the green arrow.

Row 4 – 13: repeat rows 2 and 3 with Hot Pink

Row 14 – 25: repeat rows 2 and 3 with Coral

Row 26 – 37: repeat rows 2 and 3 with Tangerine

Row 38 – 49: repeat rows 2 and 3 with Marigold

Row 50 – 61: repeat rows 2 and 3 with Yellow

Row 62 – 73: repeat rows 2 and 3 with Celery

Row 74 – 85: repeat rows 2 and 3 with Seafoam

Row 86 – 97: repeat rows 2 and 3 with Thistle

Row 98 – 109: repeat rows 2 and 3 with Mauve

Fasten off and weave in all ends.

Love Life Yarn has a wonderful video tutorial for the mixed cluster stitch (below). Note: At the end of the cluster row, she works an HDC. I used a DC because I found that using an HDC caused that edge to be too tight.
