These marbles are both just over 1 inch.

I made these marbles recently. The smallest is about 3/4 inch, the largest a little over 1 inch.

These beads are a Boston Terrier and a Bulldog. They are about 1 inch across at the head (the ears are a little wider.)

The two larger beads are purple and a shimmery orange. The smaller bead has multi-colored frit (small pieces of glass) partially melted into the surface.

I have been making glass hearts. These are from 1 - 2 inches long, in various colors. They hang at an angle.
