Remix: Create a magnificent Scrabble Bulletin Board using your old Scrabble game Inspired by: Crafster.org

Materials:

* Old scrabble game, with letter tiles.

* Metal thumb tacks

* Strong holding glue, such as quick-setting epoxy or superglue

* 4 8" x 5.8" nails

* Drill

* Sandpaper

* Foam board

* Creativity

* A little patience (depending on the glue you use)

Directions:

1. Drill a hole on each corner of your Scrabble board. Drill holes slightly smaller than the nails you will use.

2. Glue or paperclip the foam board to the back of your Scrabble board.

2. Sand the back of each tile with the sandpaper.

3. Glue the metal thumtacks to the back of each tile.

3. When the epoxy has cured (overnight), or superglue dried (hours), nail your board to the wall

4. Put in the thumbtacks. Attach your notes. You are done!

5. For kicks, drill two holes on a wooden tile rack. Either nail it to the board or under the board. You got somewhere to put your pen.
