When I am cutting thick, puffy batting, I lay a board on each side of where I am going to cut strips to compress the batting. Just leave enough room for your ruler to cut the long strips, leave all the strips in place and then you move 1/4 of the way around the table and cut long cuts again but those really cut the long strips into small squares. Clear as mud, right. Just practice using the boards and moving them CAREFULLY so as to not move the strips/squares. I know that is a lot of board moving but it works for me. Remember, YOU are the one who has to move 1/4 way around the table and move your 2 boards veeerrrry carefully. Good Luck,
Donna
