My wife is a B roncoholic....I'd been making stylus and pens from the Gator Acrylic Blanks from Woodcraft. Never sure if they had purple or Blue in them...depended on the light. While looking for something else I fount this at Ernie's Bear Tooth Woods - Denver Swirl Acrylic Pen Blank
My wife freaked....Beautiful Orange and Blue with just a wisp of white (can you say jersey numbers)
