And now...take two
I had decided to carve the edge of the edge of the challa cover with a tool I had bought at Michael's. It is an X-acto blade attached to a heating element. I purchased it with the hopes that it would create a really clean edge. Perhaps the Ultrasuede was too thick for the blade, but I found using it to be really frustrating. So I pulled out my trusty soldering iron and found that despite the fat point on the soldering iron, I got a cleaner edge with that tool.
