All the 500 piece puzzles in this category are Cobble Hill jigsaw puzzles. Cobble Hill Puzzle Co produces high quality jigsaw puzzles with nostalgic images that create a sense of whimsy and happiness. Each puzzle is randomly cut, so all the pieces have a unique shape versus the traditional ribbon cut puzzle. Cobble Hill puzzle enthusiasts love the challenge of these puzzles as well as the beautiful image that is created from the random cut and the low-glare linen print paper that is used. The thickness of the puzzle piece lends to its sturdiness and Cobble Hill puzzles are made from recycled material. If 500 pieces seems too daunting, we suggest trying the 400 piece Family Puzzles.
