I made two tiles using a stacking technique to layer the colored glass within the clear glass (Spring Rainbow #1 and #2). They are very similar but are sold separately. Each tile is about 4 inches on each side. I will send your tile with adhesive rubber feet enclosed so that you can use it as a coaster, but I will let you add the feet because you could also glue a loop of wire or a finding to the back and make the tile into a suncatcher if you prefer.
Spring Rainbow Tile is $10 plus $5 shipping. Please read the About information before you buy any glass.
