We offer puzzle frames HERE.
Frames have plexiglas on front and back, so you can see the intricate cut pattern form the back.
Choose which size frame based on the size of your puzzle. In the order comments section, specify which puzzle the frame is for (just the title, we don't need the dimensions). Frames and plex are cut to exact dimensions of your puzzle, and come with assembly instructions.
You do not need to glue your puzzle to frame it. We do not recommend glue, and we have not tested glue on our puzzles. We suspect most any glue would work, although we'd recommend gluing the back side, not the front.
To move your completed puzzle, cut two pieces cardboard the same size, slightly bigger than puzzle. Slide puzzle onto one piece of cardboard, put other piece of cardboard on top, you now have a puzzle sandwich. Tape sides and you can easily transport in car. You can also use the puzzle sandwich to flip your puzzle over by pressing cardboard pieces together and flipping.
