SherriFoster Fantastic Puzzle Mat - Fantastic puzzle mat for beginners or experts. Easy to use and set up. The large sized heavy duty felt mat holds small to large puzzles up to 1500 pieces. The mat is great for puzzle working. It holds the pieces in place and keeps them from sliding all over the table or being knocked off to floor. My puzzle pieces showed up very well against the contrast of the black felt mat, making finding the right piece all the easier! We completed a 500 piece puzzle as a family fun activity and had a blast! The convenient roll up storage tube is simple to use, takes up minimal space, and keeps our creation safe until we frame it! I have used other puzzle mats that had thinner felt pads and did not lay flat, this puzzle mat by Wood Expressions is one of the best I've tried. Definitely recommend.
