I am working on my 88-note push-up Pianola, and I want to change the
old felt pads at the tips of the fingers.  I am looking to buy a 3/8"
thick sheet of felt at about the density of piano hammers, so that
I can punch or cut out circles of about 1" diameter.  When I cut the
circle in half, I will have two felt pieces with one flat side for
gluing, and the rounded side for touching the keys.

I have tried several places, and I cannot find this material anywhere.
Does anyone have any suggestions?
