To simplify construction of a straight sided top quilt I put together a spread sheet to give me the measurements for cutting the shell material, baffle length & spacing as well as how much down per chamber. See http://www.hammockforums.net/forum/s...ead.php?t=4362 for a walk through on the actual TQ construction.
I included examples from HammockGear.com to help people decide on their desired final specifications. I also included a cost comparison tool to help folks decide if they really want to build one themselves or just order from one of the cottage manufacturers. I'm on a budget so it's DIY for me.
