Curved Poster Board

[athabascamaverick]

Does anyone have a trick for taking a slight curve (like from storing on edge) in foam poster board? I want to use it for the "flat" roof of a building but I don't want to attach it to the walls (removable so you can see the inside). The piece I have has a slight curve I need to straighten.

Set it on a flat surface and put a book , board , whatever atop it to weight it down flat for 24 hrs or so .

Under a weight on a flat surface is going to take more than 24 hours - I've had it like that for about 36 now and it doesn't seem to have changed the curve much at all. - I think I'll try the iron trick - Laurie, can you define "cool"

Ha ha yes not as hot as hot.

Can you experiment on an odd piece rather than wreck the whole piece. Just take it in increments turning up the heat.

Perhaps using steam. But experiment best.

Thanks, I do have some scraps from cutting the building sides - Guess I'll see how hot melts foam board
