I've been taking an Uncial calligraphy class with John Rafter, through Mount San Antonio College.He's a very thorough instructor and I've learned quite a bit about refining this hand (style) which I've studied off-and-on for years.
For all my ATCs, I'm determined to use mainly on-hand materials. The background here is scrapbook paper, purchased years ago, glued to stock cut from an old rolodex card. The strip of text is snipped from a Japanese novel, layered on top of green and gold pieces cut from scraps of paper. The embellishments are from a package of little self-stick "gems".
