Here are some ideas. Think about what quilts you really like, and possibly you could make a name tag in that style. Do you like landscapes? Or maybe modern? Do you like quilts that are embellished with beads, buttons or ric rac? Possibly you really like applique? Maybe you like traditional blocks, such as stars. Also, think about what type of fabric & colors you love... civil war, Kaffe, batik. If you're really not sure, check out the 6" blocks on quilterscache for ideas. Also, think about how you are going to attach it to you: with a strap around your neck, a pin on the back, maybe a magnet.
Write your name on a piece of paper and trace onto Solvy interfacing or quilting paper. Stitch it on with a simple backstitch or chain stitch using DMC floss in your favorite color. I think a varigated would look nice also.
