I had a question about the Gossamer Gear's polycryo ground sheets a couple years ago and they told me to use a couple pieces of tape to separate the sides of the sheet, they are cut so cleanly, you can't peel the sheet apart to get the advertised width. Now I see they come with a note on what to do. My fault, blame me.:)

When I ordered my second Jag Bag silk liner, I messed up and ordered the rectangular size instead of the mummy. I emailed them and got permission to send it back, I received the correct one in a few days. I know the one I sent back hadn't reached them yet but they trusted me to do the right thing.
