Knit in the round on double pointed needles (dpn) with regular worsted weight yarn, these can be made either long or short, whatever suits your style. The bows are made as you go and the knitting pattern includes photos to show you how to make them.
A few quick words on sizing. Instead of going through all the effort to remake the pattern for different sizes, and to keep the proportion of the knitted bows the same, I’ve gone about adjusting the sizing by changing the size of your knitting needles.
