Re: Jerry can & fender covers material?
Go to the Sailrite website. They have all the materials and also tons of (mostly free) instructional videos that you'll find very helpful in getting you started on many different kinds of sewing projects. Over the last few years I have made a ton of stuff for my boat, including storm sails, bimini, cushions, sail covers etc. from their kits and materials. They have a good material for doing very strong fender covers that I have used.
