I love my squares! Right now the biggest one I have is a 16 1/2 x 16 1/2. I put cans of veggies on it to help hold it in place when I cut so it doesn't wiggle any.
I do know there are some brands that I don't care for at all because of the "fat" paint lines on them...it really can make a difference if you don't use the same "side" of the "fat" paint line cause you can end up 1/16" to 1/8" off on each cut. Seems silly until you add up all of those 1/16" and tada you got a problem at the end of the row.
