Assembling a jigsaw puzzle is both time-consuming and exciting at the same time and after we finish it, some of us feel bad to take it apart and put it back into the box. For this reason, many prefer to frame the puzzle and preserve it for the years to come. It is very cheap to do so plus it is very simple and fun to complete the process. Here is what you should do:First of all, you need to verify the dimensions of the puzzle (check the box) and cut your cardboard / poster matting the correct size. Make sure that your entire puzzle will fit n the board. After verifying this, you must place the cardboard mat / poster board on the table before starting the puzzle. Now, assemble the pieces on top of the mat. After you have finished the puzzle, use puzzle glue in order to seal lip plumper all of the pieces together. The glue must be applied liberally around the edges.We recommend that you let the glue dry for about 24 hours or so and after that, gently slide the puzzle off the board matting. You might need to gently pry the puzzle off in certain places, if it has stuck to the board. Now it is time to apply the puzzle glue to the board matting and make sure that you cover the entire surface evenly.Take the finished puzzle and place it on top of the aforementioned matting board quickly, before the glue dries completely. Now, press down on the puzzle in order to make sure that it has adhered completely. Wait a night for the clue to dry entirely.Use a standard picture frame that you can buy from your local department store, art shop or even local thrift shops.
