Material experimentation: Wire and thread

To begin experimenting with the feet of the maquette, I decided to make some scaled up prototypes to see what kind of materials worked well together.
For the first one, I simply wrapped red cotton around wire that had been twisted into the desired claw shape. The cotton was wrapped tightly until the whole foot was covered, then the thread was secured with PVA glue.

I like how this prototype worked out, but feel that it looks a little thin? So would like to experiment with layering and making it thicker, or a use of thicker materials.
