I also make lots of beads like the ones below in various colour combinations:
Sometimes I use transparent glass as the base and sometimes an opaque but it's always a solid colour with no coloured core or inclusions. The decoration is all on the surface of the bead and always an opaque glass. Basically I just doodle on the beads to my hearts content and generally the doodles are dots, so this style of bead sets are going to be called Dotty Doodles.
I have another 10 days of manic bead making before the Crafts 4 Crafter's show - just need all the marketing stuff I've ordered to arrive now! I did force myself to "step away from the laptop" when I found I was hovering the mouse over the "add to basket" button to purchase a t'shirt I could stick a picture of my beads on ;)
