Looking to make an UQ or two. One out of a Neat Sheet (NS) and the other from a sleeping bag (SB). I have seen that some UQ have tabs sewn into the corners which allows cordage to be attached via mini biners. And I have seen channels sewn down the edges of the UQ allowing the cordage to run the entire length of the UQ. Is one way better than the other? I'm thinking full length line for the NS due to its weight (or lack there of) and tabs for the SB...? These would be for an ENO double. Any suggestions?
