I've used many patterns, knitting, crochet and sewing, that designers have generously shared for free online so I decided it was time to add my bit. When my daughter was unable to get a Mog the Forgetful Cat for my grandson she asked me to make one. I started with a pattern by Runo for her Ragdoll Kitten and went through 4 prototypes before I got her right made from cotton fabric. She's turned out a bit fat in fur fabric as the only fur fabric I could find is a bit long but it's very soft and cat like.
If you want to have a go the pattern pieces and the instructions are here. Mog is about 25cm tall.
Let me know how you get on (contact details here) and if you find any errors I'll do my best to correct them.
