Sometimes I enjoy doing jigsaw puzzles because of the pretty pictures. I like to work them while sitting on a bed, with my children. In order to avoid frustration, we use Scotch Magic tape to tape each piece together. This ensures that we will always be able to put it away unfinished and yet start on it again the next time, right where we left off.
We have done 100 to 300 piece puzzles this way. It works out great for us and allows for family time without fussing about having a table for the puzzle. ;)
