Just thought I'd do a quick post to let you know where I am with the puppet...
It's in bits.
Actually, that's not entirely true. I've restitched the left hand side, and I have the neck / head seams to do. The biggest change however, is that I've ripped the mouth felt out! Yup, I got sick of seeing that ridge, so I've pulled it all apart and I'm currently planning on putting a piece of black felt in, and using Hi-Tack glue as metioned before.
Extra bits I've just purchased include eyes, silicon tubing and wire - why they are required will become apparent in the fullness of time..... :)
