I made Cere and Bella's claws last Monday, they're now ready to be sewn into the paws. Each rat gets 20 claws, but I made a few extra just in case. As you can see, they're like little pearls, the hole allowing them to be fastened securely to the inside of the paw. While fragile, the Fimo is more durable than you'd think!
And, old dogs do learn new tricks: I discovered making these wee things is a lot easier if you cut the clay into small slivers first rather then tearing off pieces from the larger lump.
