I am obsessed with rainbows. I have a rainbow fish didy babywearing wrap, and a rainbow blanket for my son's room and...now a rainbow puff hat. Somehow all three of these things must make it into a picture together.
For this tutorial you will need worsted weight yarn and a 4.0mm crochet hook and an obsession with rainbows. You can download and view the PDF file here on Ravelry, and see the YouTube tutorial on my channel.
