Those are pretty cool how do you make them ?
I'll give the basics here:
1) Borax the beard.
2) Band saw trim shells and legs.
3) Punch primer out of shell.
4) Put spurs on a wire and boil, 10 minutes ish, with a healthy squirt of Dawn dishwashing liquid and big pour of Borax.
5) Trim skin and scrape bone.
6) Repeat step 4 if necessary - You don't have to change the water.
7) Put 40 Volume Creme (buy at Sally Beauty Supply) on spur bones. Let it sit overnight.
8) Wash/brush off cream and repeat step 7. Usually twice will bleach em good enough.
9) Spray paint spurs, still on wires, with high gloss clear paint. Shake em the first couple minutes after painting so you don't get drips off end of the spur. Two coats is usually good.
10) Braid some 3/32" (2mm) strands of leather. I like the suede. Larger strands are difficult to stuff thru the bones and the beads and the shells. Buy the leather at craft store, like Hobby Lobby. Buy some beads while you're there!
11) Thread/loop the leather thru the shell, beads, and spurs like you want em. A knot on the end helps keep the leather in the shell.
12) Trim the beard and test fit it in the shell,
13) Use a hot melt gun and squirt some into the shell. Then stuff the beard in and hold it a minute. Wear a glove and use low setting. Hot will melt the shell.
I took a couple of pics while I was doing these. I'll post them in a follow-up.
