Interested in the mosaic craft technique but want to start simply? Here’s a wonderful way to "rescue" a jigsaw puzzle that isn’t giving pleasure in its present form… put it on a box instead of in one! 

Start with a nicely-finished box suitable for use as a gift... Cigar boxes work well if you want a lid, because the layer of puzzle makes trimming lap-over lids difficult. Wooden tissue box covers are pretty good candidates. You’ll need to put the jigsaw puzzle together one last time! (This is a good way to use puzzles with missing pieces, as long as there are swaths of whole puzzle that will fit the surfaces to want to cover.) Cut put-together slabs of puzzle carefully to fit the faces of a box. Apply glue to one face at a time, press its slab into place, and allow it to dry. When all the surfaces are covered, you can paint and seal the whole. ...Or did you want the design to show? - then just clear-seal the result!
