I'm new to posting on BPL, but have been reading the forums for awhile now. Great community! I'm looking at making some of my own roll-top (with clasp) dry bags out of Sinylon or Ripstop Nylon with DWR or other waterproof material.
Does anyone have a materials list or plans on making various sizes of dry bags? I'm actively involved in Cub Scouts and we go on a ton of canoe trips and other water activities and would like to make some of my own gear. Sewing the bag material is easy enough, but getting the right materials for the roll-top strapping/support is where I'm confused, along with some good sources for waterproof material.
The search function isn't working for me as planned. Any information/ parts lists/materials suppliers you could provide would be very useful. I'd like to make a dozen of these and give them out as gifts to the scouts. With that said, these don't need to be ultralight Cuben material, but any cheaper waterproof material would suffice.
