It will mold very reluctantly at boiling water temperature. I'm guessing
50-100 degrees above that, but have not got around to trying it.
The mold I made was initially a 3" PVC pipe cap machined to a more
rounded shape. It was hard to hold the hot plastic against it, so I
machined another PVC pipe fitting to be the outside. Put a flat,
circular piece on the inside, push the outside ring down around it and
let it cool. With a little more fumbling as to temperature it should go
pretty good. I was experimenting with boiling water temperatures.

I know that Joann's has it if you have that store around. Not sure I've
seen it in Michael's.
I did a quick google, look at the Latch Hook Backing shown on this page,
that's what I'm talking about:

I just searched on rug hooking, probably a bunch of what turned up have
the material.

It would have to be pretty coarse. Unfortunately the plastic canvas egg
and sphere are too small.

Commercial fur covers are generally slit along the bottom and maybe a
couple back slits so they can be slipped on. Zippers or snaps are
generally used to close them.

The Sennheiser zepp has it's fine material on the outside. I'm not sure
it makes a lot of difference. Rycote's lining material would wear out
fairly fast if it was outside, Sennheiser is using a extremely fine, but
strong mesh.
