Chamois pads can be purchased and added to stuff. I buy mine at Seattle Fabrics (http://www.seattlefabrics.com) and have put them into storebought lycra tights and shorts, and have contemplated making my own bike shorts and jerseys. I'm very tall and not exactly svelte so I'm having the devil of a time finding stuff to fit me, so why not make it?
I'm very pleased to find other folks making their own cycling clothes!
How IS that Jalie pattern? The Green Pepper bike patterns kind of suck.
