Here are the basic materials you will need to get started. I used 14 Gauge galvanized wire for the main structure, and 20 Gauge galvanized wire to tie it all together. You will also need foil and some masking tape, but that comes later. A good pair of wire cutters are needed to cut galvanized wire (not shown), you can also use copper, or regular armature wire. But I feel galvanized is the most structurally stable. You can find all this at Wal*Mart pretty cheap!
For the feet it can seem a little tricky.. hopefully this will help a little. I start by making basic shapes: The front pad, and 3 cones. I also made 4 sets of these shapes so I can get both feet to match better. For this dragon the back feet look a little different having a clay in the heel. And the front also get an additional opposable thumb. But since all 4 feet have 3 claws I made sets for them all. These quick and easy feet can be added to the rest of the foot no problem.
Once you have all the pieces made up, attach the 3 cones to the front pad. Then cover that with a layer of clay to cover the seems. This will also give you the cuticles look [NOTE: this method does not yield finished results to the bottom of the feet, these feet will be placed on top of a slab of clay to hide the bottoms (shown in photo) the pad will also help protect the claws from braking off]
