Framing a puzzle can be tricky, but it is possible without ruining it. You’ll need a high-quality frame to put your puzzle in, as well as matting and backing. To avoid damaging your puzzle pieces, apply an adhesive to the back before placing it into the frame. This will hold the pieces together without adversely affecting them. Additionally, when fitting the frame, put it a few millimeters away from the puzzle itself so that no pressure is placed on any part of it.
