I admit, I had a 'Dragon Phase' in my art during my High School days, and came up with a number of my own passable designs. Here, I try to show one that was traced onto the side of a wine glass (by others), which I made a small number of to sell at art fairs. Due to the 3D nature of the piece, and that the design wrapped around the diameter of the glass, it may not be entirely well shown here.

Technical Details:
Material: non-tempered 16 ounce volume wine glass, clear
Fabrication time: 2 hours, give or take
Tool used: handheld mini-drill with diamond carving tip
