I just did this to see if it’s something I want to pursue.

Here's what I "wound" up with.

I used 2 8.5” squares of cheap foamcore glued in a stack. I recommend using 3. The stringing part took about 5 min, and that was with having to be delicate with the foamcore. If you’d like to play along, here’s a template I put together.

Cut out the circle and only pin down the bumps. This will make it easier to center and remove.
I think I’ll take this craft seriously.
