So just for fun last night I popped Sonata onto my creature(which I think I've decided to name Feer); and it totally worked. She sits very solidly on his shoulders and he's super stable thanks for his wiring. He can even be posed reasonably with the doll on his back!
before stuffing the body I measured out how long each wire for the body/tail and legs had to be, then I twisted them together at the shoulders and hips, after which I wrapped the connections in masking tape to solidify them. I also made large loops at the end of each leg wires to give him more stability. Once the wire skeleton was built, I slipped it into the plush then stuffed him.
I just bought my first 2 in the space of a week, waiting for them now :U
That soom is gorgeous as is the plush. Great colors
your idea turned out really well!
