Gonna give it a try:
Wrap hook with thread, it gives the foam a decent base to adhere to.
Cut the foam to fit the hook.
This is the tool I use to turn down the bodies:
Use a dremel tool and emery board to turn down the body:
Use a razor blade to cut a slit in the foam body:
Put the body on the hook using super glue, or zap a gap
Paint scales, put eyes on and coat with Liquid Fusion.
Now you can thread the legs and put whatever kind of tail you like on the back. I have a small bit that I use to hollow out the front of the popper, but it's not required. Hope this shows how I do these poppers!
