Any worsted yarn will do. Hobby Lobby’s I Love This Yarn is perfect in texture and size, but I couldn’t find all the colors I wanted. I noticed that Vanna yarn did, though.

I used some old Berella worsted scraps for my inner colors, along with white HL because of how soft it is.

This is a super easy pattern, worked in all DC’s.
You could just as easily knit it in garter stitch instead, if you prefer.

I LOVE the idea that was posted in comments: how about making scaled-down versions for kids (maki?!) hehe!
