The Cobble Hill Family Pieces 350 Puzzles offer the opportunity for puzzlers of all skill levels to contribute to the assembly of a fun family image because they have three different sized pieces within the puzzle! These special puzzles have more large sized pieces on one end for those who need more imagery per piece, as well as a larger surface area to grasp. Plus, there are a good number of medium sized pieces too, so nobody feels "stuck" with too many "small" pieces. Large pieces are on one side of the puzzle and small pieces are on the other side. This allows people of different skill levels to work different sides of the puzzle at the same time. We hope your whole family enjoys these lovely puzzles!
