Here are my supplies. Using a box cutter would probably give you a straighter edge. I wanted to put my own spin on it.
Almost forgot the paint I used to 'age' the tiles (wipe on/ wipe off).
I went with a thick cork board because I wanted a substantial piece.
I love it for it's imperfections.
The project cost me $7.50. I would try to find cheaper scrabble tiles next time.
-Glue gun and tiles from Anazon.ca
-Cork trivet and craft paint from Dollorama
Let me know if you have any questions.
