Mini Rabbit can be made with any yarn and hook size, though my preference is with 8ply cotton yarn (Australian sizing) and a 3mm hook!
Each Mini Rabbit takes around 25-30g of 8ply cotton yarn; I typically use a single colour, but you can add your own colour changes as you desire.

I embroider the nose and eyes in 8ply cotton yarn as well - but you can use any yarn you would like
