Today I glued the bottom half of frame #3 (the last piece I made was the top half). This one behaved pretty well as far as the gluing process went. The ends might have twisted a little bit but there is extra that will be cut off so I don't think it will be a problem. I tried doubling up on the cardboard padding this time to try to get rid of the dents on the inside strip so I'll check on that when I clean it up.
