These are some tile coasters I made last year to sell at craft shows. Thought I'd post these in case anyone could use these for gifts or to sell.
There's lot of nice ones in the gallery for these too. This is a technique I got mainly from Gina K in the Resources/Tutorials under Tile Coasters.
This picture shows how I package them up to sell at craft shows. I used 5 1/4" x 5 1/4" clear bags with stickey closures (clearbags.com) and shredded paper. The topper is cardstock cut 5 3/8" x 3", score at 1 1/2". I sold these for $5 each and they sold really well for gifts.
