Heart of Glass
To make the heart bottom left, use four 1x1" bevels and 2-2" half circles. You can also make it large by using 4- 1 1/2x 1 1/2 bevels and 2-3" half circles.
The large heart in the center is made with 1-1x1" bevel, 4-1x2 bevels, and 2-3" half circles.
The heart on the bottom right is made with 1-2x2" bevel and 2-2" half circles. You can also make this one large by using 1-4x4" bevel and 1-4" half circle.
Word to the wise. If you use copper foil, be prepared to patina your solder copper. If you don't, the copper from the inside of the tape will show through. If you don't want to use copper patina, use black back foil and patina it black or use silver back foil and leave it silver.
A variation of these hearts is to replace the half ciricles with red or pink glass.
