Make a glass bubbles coaster from transparent fusing glass and trapped air bubbles within a glass stringer grid.
The glass and stringers are placed over a grid template and then glued in place.
When fused, the glass bubbles coaster has rows of evenly spaced rows of air bubbles trapped between the stringer grid.
The coaster is made from Bullseye three and a half inch square transparent colored fusing glass and stringers.
System 96 may be used in place of Bullseye.
The coaster size and transparent colors can be varied.
