Great question. I think I would try to lay mine Flat in direct sunlight. Let gravety take care of it.

My 36" by 36" goes behind the bookcase when it is not in use. But all the others stand up on the top of a cabinet I have all my patterns in. All my rulers store there too.

I think the warp is here to stay. It says so right on the packaging label.

I used to keep them under the bed or couch. When my DH redid my sewing room, he raised my cutting table about 6" and created a space between the old and new tabletops for storage of mats and rulers.

Cathe, I really like that idea :D :D :D

Guess I should be more careful with my mats, but really don't have a problem with warping, even though I store them behind a closet door when not in use, which is seldom.

My problem is finding a self-sealing mat that doesn't wear out. :roll:

What a great idea! Where my DH, I have a project for him. :idea:

Cathe that is a great idea. I think I can have the hubs create something like that when he builds my new ironing table.

i am re-cycling a dresser that was 'found' on the side of the road. it has big, wide drawers. ugly as all get-out, but it holds all my cutting mats and my revolving one that dh made for me. my mat is the big one.

we bought a lazy susan base at home depot, very sturdy. he attached a plywood square to it. in my case 16 or 18 inches (?). glued on the cheapest mat we could find that covered that wood. voila! a HEAVY duty revolving mat. HEAVY being the operative word, here. boy, can you lean on this baby!
