Is there any way of flattening out a self-heeling mat once it gets a ripple. I have 2 like that. I didn't realize they were under my ironing pad!

I have heard this works, but try at your own peril! preheat oven to warm, not 350. Turn off and place cutting mat on flat cookie sheet in the oven to relax. If you try this, let me know how it works for you. Just make sure that your cookie sheet is big enough. You might try doing the same thing in the trunk of your car on a sunny day, I know they get wrecked that way, maybe that can fix them, too.

I am going to try to glue one down to a piece of plywood to see if that will work. Other than that possibility, I haven't heard of anything that will work.

Thanks, I'll try! Have tried putting over heating vent, ironing under towels then pressing, hot water. piles of books... *Sigh* Maybe I should contact customer service at the maker's web site.

Ooh, the plywood trick might be good to use when its brand-new!

that is terrible, I hope you get it fixed

I would not glue to plywood! You will loose 1/2 of your mat. When mine gt to bad I flip them over, voila' a new mat!

Yah, but they still have the ripple! I'd not use plywood, but some stiff cardboard or something. I have a free counter space and a second bad board that I could actually glue to permanently! I'll let you know. (No DH to say I can't!) Like I put nails under my sewing table to keep the peddle in place!

I just bought a quart of contact cement to try this very thing. I figure the mat is ruined to start with so if it doesn't work I'm not out anything. I have a scrap of plywood and am gonna have friend go around it with his router to smooth out the edges if it works. Maybe I should add this to my long list of weekend chores.

Maybe the 'spray' adhesive would be better than brushing on rubber cement? It should be more 'even' that way verses having uneven areas bkz the glue was heavier in some areas. Just a thought.

okay, at least use parchment paper if you're going to put it in an oven, though i think i'd just buy another.

also, have you considered using a pizza stone or piece of untreated quarry tile in the oven?
