I finally got hold of a thread injector and am trying to learn how to use it. I have a piece of coated nylon and am going to make a square bottom stuff sack to try and make a synthetic mummy bag fit better in the ULA Circuit I bought for my wife. I have my pattern figured out but I'm not sure if I should put the coated side of the nylon "inside" or "outside". Any recommendations ? What is considered the "right" side of DWR ? Thanks, This forum is the BEST..!!!
