Silnylon is a super lightweight fabric that is used for many things including tarps and stuff sacks. The Silnylon Tarp shown here was created using a pretty standard home sewing machine. It can be a little tricky to sew as the fabric is impregnated with silicone which is fairly slippy.
However with a little patience you can produce some pretty nice kit. One of the hardest parts is actually getting hold of the material. In the UK this isn’t easy but many of the US suppliers will happily send fabric out.
These little attachments for the guy lines are superb. I have a got a huge bag of them ready for future projects.
