I recently purchased a few puzzles from Dollar Tree. One was this 100-piece titled T-Rex Dinosaur, and it caught my attention because of the colors!
I was planning to assemble it over a couple of nights, but I was enjoying the process and with the small size (8 3/4" x 11 1/4"), finished it the same evening. I covered the top with Elmer's glue (saw this tip in a video) and placed under some heavy items to ensure it dried flat. Once dried, I adhered it (used Aleene's original tacky glue) to a piece of black chipboard I cut approximately 1/4" bigger than the puzzle. The puzzle has rounded corners, so I used the corner chomper tool to round the chipboard edges to match. A simple way to finish and display on an easel.
