Finishing

1. Sew two sides of mouse body together from tail end to nose end - I'm going to try knitting it on double pointed needles next time to avoid having to sew it
2. Insert stuffing and catnip into mouse body.
3. Finish sewing body right up to the tip of the nose.
4. Sew on ears using cast on yarn ends.
5. Crochet single chain for tail.
