Not hard, just fiddly for the fluffy bits. But it is explained with a video by the creator of the pattern. All the other stitches are classic single crochet and slip stitch.
That being said I wasn’t too happy with how the pattern was written overall. Nothing insurmountable, just not what I am used to. Instead of “(2 SC, INC)x6” it would be “sc in next 2, 2 sc in sc, repeat the whole round” for example. I’m just not used to that writing style and I had to really concentrate to avoid making mistakes.
Missed opportunity to have the dancers have alternating skin colour and add some interesting patterns to the dance.
