This very large puzzle was cut for use as a church fund raiser, This puzzle is a rare grid cut (also known as "strip cut") puzzle from Custom Puzzle Craft. This puzzle is different from my first grid cut style puzzle Tarsadia Hotels in that the pieces have sides which curve back and forth from piece to piece, while the first one had straight sides between the interlocks. The large puzzle size and hefty pieces made this grid cut puzzle fun to put together!
