Although this tutorial is about making vases, it applies equally well to making tumblers. First create a template by wrapping a stiff material around the glass and trimming it to size. Roofing paper works well for making templates for clay handbuilding. Building it over the original glass helps to hold the structure. Baby power can be used instead of a non-stick liquid to help the clay to slide off. Don't forget to add a bottom.
Wind Chime: ceramic hemispheres hung close together create long body of a fish with -I'm sure- a great sound chime. Could be done with your own clay but also upcycled old tea or espresso cups for this same thing, fish or not. Cute!
