Thanks for the hint. I will definitely use it with my new rotating mat.

Mary O -- you've helped out alot of boardmembers by the look of these posts! Hopefully if you try the hints given of warming it up and flattening it down you can get it usable again.

I like the idea of storing it under the rug. I store all of mine under my couch in the livingroom.

You would think that mats in any form could be made of non warping material because lots of quilters travel. Hot cars are the worst. I better go find a better place for my mats instead of leaned up against the wall. Thanks!

Put it in the hot sun sometime. I've taken cutting mats and laid them out in the sun. Works even better if you lay a piece of glass on top. They do get flat again.

Thanks so much for posting this. I had mine stored on end and now it's stored flat.

I hang mine on a skirt hanger in the closet.
