This is the pattern for a rainbow appliqué. I do have this pattern available for free on my website if you would prefer that option. The link is down below, but I’ve made it available for people to download as well for $1 on Ravelry.
There is also a video tutorial for the pattern available on my YouTube channel at Crochet Rainbow Tutorial.
I’ve used 2 ply cotton and a 1mm crochet hook but you can use different sizes depending on what you’re most comfortable with.
