The Forever Tree Wood Puzzle is a fun alternative wedding guest signing unit available in two sizes. The outer frame is solid wood lightly distressed black. The Frame serves as a building tray for the puzzle pieces. This puzzle is available with 108 or 150 individual pieces lightly spray painted silver on the back so your guests will know which side to sign. The whole puzzle count includes a central oval piece that is engraved Together Forever, two doves and a heart for custom engraving and three apples. Made of fine sanded Birch wood. Most people choose to have their names engraved on the doves and a date on the heart. I have hand drawn each puzzle piece and cutout with a laser engraver. A sharpie is required to sign wood.
