Hi Pete. If you look on page 7 of my photo album, you'll see a pen I made with this. It has greenish and greyish in it. And the one on the first page of my album that's white and black may actually be this instead of corian, as I labeled it. I liked using it a lot! It turned very easily. I got mine from a guy on ebay and somehow he layers thin strips of it together, and then twists the whole blank. I don't know how he does that, but I sure like the result! Here's a link to the last set I bought:

I actually picked what colors to have together and then he did them exactly as I requested, and as you can see, the price was only $1 per blank, plus shipping. I told him I thought he was charging too little, which I still think, b/c it has to involve some time to do all of that. The hardest part for me was drilling but I figured out a way to handle that too. I'd sure recommend trying it. People have really liked the patterns the twisted ones make.
