Hi all, I purchased a lithograph from a concert but i noticed it had a crease in the middle of it. I exchanged it for another, but it seemed like the entire batch had creases in them. My question is how can I remove the crease? I've tried lightly ironing it and I think it has removed it a bit, but it's still there. I don't think putting it under something heavy will work either. via /r/DIY https://ift.tt/2Hg5FPL
