Welcome to the Rainbow Baby Wall Hanging.
This is a crochet pattern.
For this pattern, you can use any weight yarn you’d like. I used Knitpicks Wool of the Andes which is a worsted weight yarn and my wall hanging turned out to be 10 inches wide by 12 inches long. Again, you can choose any sized yarn you prefer, just know that your finished wall hanging will be a different size than mine!
For a worsted weight wall hanging, use a 5.0mm crochet hook. For any other sized yarn, just use the suggested crochet hook size listed on the label!
