Our family has always enjoyed putting together jigsaw puzzles; we have dragged them out for Thanksgiving and Christmas, as well as simple get-togethers for no particular reason.
While we are visiting our daughter and granddaughter, we pulled out a small (14 x 10) puzzle, which we figured the three of us could work in about 15 minutes.
Ha!
The puzzle is cut from wood, and all the pieces are different. There are no corner pieces, so you have to look for triangular ones that mesh. There are lots of bits with flat edges, but they might go in the center someplace as easily as on the outside. The picture is of Omni Grove Park, a golf course near Ashville.

It was small, but it was mighty, and it took the four of us over two hours!
