Hey all, just wanted to throw this out there:
Just received a nice 9.5x10 sil tarp from here. Everything is made to order; I actually spoke to him on the phone to clarify exactly what I wanted. The price was great, shipping was quick and the finished product looks to be good quality. I set it up today in the woods next to my work, and I can't wait to use it out on the trail.
His store also makes tarp-shelters, bivy's, and tents of the minimalist nature, as well as sells materials to DIY. It's worth the look, check it out!
