I got my Climashield in today and I cant wait to get sewing! However there is one problem... I don't have a pattern. Do i just sew together two pieces of ripstop both with the same width or should one be wider than the other like an under quilt? This will be my second time working with ripstop (I made my dog a tent to keep him a bit warmer in winter) and I want to start off on a good foot. I will post pics and weights when its done. I am hoping to make this a 20* quilt ( I sleep super cold) so it will not be a feather weight. I decided to go for comfort.
