Coastal wave baby afghan, I named this free crochet pattern because of its wavy design, made using easy single and double crochet stitches, I hope you enjoy making it.
The blanket has been crochet using a worsted weight #4 yarn (Aran for UK users), it’s perfect to swaddle your little one in or make for a gift.
