I use a fiskers roller cutter to cut foam and a June Taylor Shape Cut Too
cutting guide for cutting foam I got the cutter from wall Mart and the Guide
from a fabric store It has a guide with slits for the cutting wheel to go
in.
It does a beautiful job for cutting foam as narrow as 1/8 wide. Probably
narrower but I never tried.
For foam ants use a sweeper nylon bristles for the legs. I looked at several
before I found the right one. I have a pattern if I can find it. It does a
beautiful job. The things look so real I wanted to kill them after I got
them tied. Check with me later
