of course- if you are able to make gear why buy Byer? I know there are instructions for gathered end hammocks and deployable bugnets on this site- taffeta (nylon or polyester) and chiffon are cheaper than sil and nano-seeum.. and just as effective.
Just sayin...

PS - more specifically; for hammocks taffeta is a good start- ripstop is better and sil makes the best tarps, but you have one of those already. still think chiffon (nylon/poly) makes the best bug net- and so many colors!
