This is my first project so I'm a little anxious about it. My goal is to make a summer quilt that can double as a over bag for my 40 deg bag in winter. First off I don't even know if the over bag idea has much merit as I haven't heard much about it.
Now for the quilt itself. I was planning on using silk for both the shell and the liner. Are there specific types of silk that I should use or ones that I should stay away from? I read something about that in threads in the past but can't locate those threads anymore. Any advice on silk would be welcome.
For the insulation I think I'm set on Climashield of some sort. Since its only for summer use I was thinking one layer of the combat from thru-hiker would be best. Is that overkill? Could I get by with the 2.5 oz/yd XP? These are the things that I want to be certain of before I start. You guys have a wealth of information and I'm hoping you can help me out. Also any advice on quilts overall or quilt construction would be welcome too. Thanks.
