Now that my Klingon-language cross-stitch is done, I need to start designing a few more. My brother has already requested a cross-stitched version of one of the Ferengi Rules of Acquisition, and I'm nervous but curious about trying to represent the Vulcan writing system in cross-stitch as well.
My brother also suggests using one of the Hylian writing systems—I'm particularly fond of the katakana-ish one from Wind Waker—to make a sampler that says, "Well, excuse me, princess!"
