I recently ordered 3 posters from art.com that I will eventually be gluing to cardboard in order to hang in a trade show booth.
The posters arrived tightly rolled up and I have unrolled them facing down with a heavy object place on top in hopes of flattening them out. I remember someone saying there was a technique using a warm iron and a damp towel that would remove the creases and flatten it out.
I really don’t want to ruin these posters, and I’ve tried rolling them backward in the past with poor results.
Is there a quick and easy way to flatten out rolled up posters using a warm iron that someone has tried and knows works?
