Diagonal Rainbows Baby Blanket


Marie Segares/Underground Crafter


I love crocheting diagonal blankets where you increase from one corner to the center and then decrease towards the end. That way, after you reach the halfway point, each row is shorter than the last!

This diagonal blanket is full of vibrant colors that will brighten up any baby’s day (or, even any room in your house)! 

Skills used 
Basic crochet stitches: chain, double crochet, single crochet, slip stitch 
Working in rows, increasing, decreasing, crocheting in the back loop only, joining new colors, working in chain spaces
