Okay, bear with me as I try to describe a frame I made for a little wall hanging that had a corner that wanted to waved in the breeze. I put the triangle corners on all 4 corners as suggested by Jen. I then measured and cut 4 1/4 inch dowels to the exact lenth and width of the wallhanging. You could just shave the dowel ends to fit the triangles but I had a little trick that I used to kind of make a dowel frame. I had saved the little connector tubes that come with the bracelets that light up for concerts. They have a little accordian pleating in the center that allows them to bend (kind of like bendy straws) They were the perfect size to connect up the dowels and go into the corners for a frame behind the wallhanging. I don't know if it would work on a 32 inch wallhaging but it sure fixed my little one.
