If you put tinfoil it will not grab. Watch Sharon Schamber's "Perfect Pressing Board"
on Youtube. I have a small board like Sharon then a big board.
I just change the board/batting/canvas when it starts getting uneven.
I didn't bother with the glue for the big one...just stretch and staple the whole
thing.
