I come across so many nifty ideas on Pinterest and have been keeping in mind what to do with Scrabble Tiles. I was overjoyed to come across two old Scrabble board games at a garage sale last weekend for 1.25 for both. So I scooped them up and re purposed them into these coasters.
I used a marine type glue (you can use a product called crafters goop too) to create a really tight permanent seal and then will likely spray them with a sealant after too. Make sure you do this in a well ventilated area and take breaks because the fumes from the glue can be quite over powering at times.
