For Otakon, I'm fixing up and redoing a lot of pieces on my Allegretto costume. I decided to splurge this time and go with real leather. I've actually had a good time working with it, and am in the process of dying and tooling it (obviously some of it neats another coat). The leather guy taught me how to "batik" it in a way, so that the dye doesn't dye parts of the leather. Very cool!
