: Sea Kayaker magazine had an article on that a while back.
: I forget exactly which one, but June 1992 springs to mind.
: In any case, I ordered a back issue from their website to get the article.

: Your local library may have it. Mine didn't.

Actually, they had a recent article in Issue 88, pg 52 (June 2002). Maybe that's what you meant Ross. It also covers other types of floats as well. Shawn Baker did a large order of heat sealable nylon recently and was due to get more. You might contact him (see the profiles for address) to see if he has some. He may have some valves too. Otherwise you can order fabric from Seattle Fabrics. They offer a free copy of the SK article with an order, but are pricey ($16.75/yd!).
