I'm attempting to make my first diy tarp. I ordered some 1.6oz ripstop - coated from backwoodsdaydreamer.com. It is almost finished, but I thought of something. One side of the fabric is like regular fabric. The other side feels smoother and looks shiny. My question is, do I need to have the shiny side up to be waterproof or is it waterproof both ways.
Thanks in advance
