Each block of wood is for one single glass tile & purchased at $5.00 each letter. Each single block measures 4x4 overall. The area where I mount the glass flag is 3.25" x 3.25". These wood blocks are great for hanging on a wall and will come complete with a saw-tooth hanger if needed. Without saw-tooth hanger on the back, just place on a table top for nautical art anywhere! When ordered, the glass signal flags are permanently glued to the wood block and can not be removed. For you crafty people, feel free to paint or stain the wood to match your décor. Wood blocks are priced at $5.00 EACH, so be sure to have the correct Quantity for whatever word or name you are spelling!
