I have framed at least 10 jigsaws. I usually do the jigsaw on some newspaper. If you haven't, just get some newspaper and slide it under your finished puzzle, making sure there is some hanging over each side. Then I get the puzzle glue (I got mine from Toys R Us), it dries clear and do one coat over the top and leave it for a day. After a day, put a layer of newspaper over the top of the jigsaw and flip it (hold your breath!). Remove the newspaper and glue the wrong side. Leave it for another day. Once it is dry again, I get contact (like you use for covering kids books) and cut it into strips and put it across the back of the puzzle.
Once you have done all that, it should slide easily into a frame.
Good luck, I think they look great when they are done.
