Find a favorite font in the font library on your home computer or look to an old type book. Print out your number or letter on typing paper and take it to your local paint-your-own pottery studio. (Look in the Yellow Pages under “ceramics” or “pottery” to find one near you.) Transfer your design by turning the paper right-side down and outlining the graphic with a charcoal pencil. Tape the paper to your piece, charcoal side down, and gently rub. The pros at the shop will show you how to ink and fire your design.
