Safely put away your work in progress puzzle with Cobble Hill's roll away mat. Sturdy "rolling pin" allows the puzzler to easily roll up the mat while all the puzzle pieces remain in place on the mat. When the puzzler is ready to assemble the puzzle again, simply undo the hook and loop straps to unroll the mat and start puzzling! The high quality felt mat is great for assembling the puzzle and keeping pieces from "escaping". It's also great for storing the puzzle, as well as rolling it up to travel to another room or place.This mat is best suited for the Cobble Hill 1000 and 500 piece puzzles in order to fit the dimensions. However, these mats can work with other puzzle brands that do not have a finished size larger than the mat's dimensions of 30.5" x 47".
