One thing I learned quickly when we moved into our townhouse years ago was that space was limited. Never having been one who could tolerate clutter, I had to find alternative methods to having "stuff." I was thrilled when I found JigZone.com. There are hundreds of jigsaw puzzles on this site, and the best part is you never have to worry about missing pieces!
There is a puzzle-of-the-day and you can choose how many pieces to play with. On days you are short on time you could choose a smaller puzzle. When you want to spend a bit of time, you can pick the 247 piece option. Do you have a favorite photograph? Upload it to the site and they will make a puzzle for you!
