Green Pepper has a chamois pattern, although you might be able to make your own pattern if you have a chamois that you like. I think the green pepper one uses polar fleece.

I made a jersey from the green pepper pattern and a kwik sew vest. Personally I like the fit of the kwik sew pattern. I didn't have to alter it, so it was easy since I am no expert at sewing.

I learned a lot from reading Irulan's site and from reading Mary9761s posts. Their information was invaluable.
