I just got done with my first MYOG project (with the help of my mom). I made a summer quilt using .9oz ripstop momentum and 2.5 climashield XP. The quilt turned out so well that I wanted to share with others. I'm recently back from Glacier were I was able to test it to its limits (and a little past). We had great weather on our 4 night trip, with nighttime temps ranging from 33f -48f. The quilt did a fantastic job of keeping me warm when temps dipped into the upper 30's, but on the 33 degree night with Caprilene 2 top and bottoms, smart wool socks, a montbell thermawrap jacket and light balaclava I was cold.
My design employed some features from other MYOGers. Small loops along the outside edge of the quilt and a long piece of webbing running through the loops lets you snug the quilt up on cold nights. I have draw cords at the head and foot. A small circular piece of insulated fabric fills the hole left by the drawcord closer keeping my feet warm. I did deviate from some other quilt designs by not running insulation all the way to the edge of the quilt.
For instance to keep drafts down I wanted a little more fabric than the 70"x48"x36" quilt "standard" but I also wanted to keep weight to a minimum. So my quilt is a little wider. The dimensions are 70"x55"X36", but the climashield dimensions are only 70"x40"x36". So my thoughts were to increase the fabric surface area, thus reducing drafts and save a couple of onces by only insulating the middle of the quilt. This design seems to have worked pretty well, I don't think I have reduced the warmth of the quilt, and with the slightly wider dimensions I have kept drafts down and increased my sleeping comfort. Another added benefit is that bulk is also reduced. This packs incredibly small!
I suppose you may be interested in the weight of the quilt and while not the lightest I think it is pretty respectable at 12.3 oz 12.8oz with stuff sack.
