Warped cutting mat

[mnwildpunk]

I have one of those hobbico healing cutting mats. I had it in storage for over a year. I did have it stored on a flat service until my girlfriend went into storage and moved it. When I took it out it was warped I tried placing weight on top of it for about a week but it didn't help. Does anybody have any ideas on how I can flatten it out?

Try heating it with a blow dryer. Good luck

Maybe electric heating pad would be more even heat.

Warm it up using a hot hairdryer or heatgun, then put a heavy weight on top, a few good size books should do the trick and leave overnight,

Hot water in the bathtub and let it sit on the bottom for a while.It worked for mine.
