I'm looking to make my first down quilt. I'm trying to understand what all my options are for fabrics.
This will be a summer quilt for moderate conditions. I'm thinking your basic 1.1oz ripstop nylon for the shell? Seems easy to find, reasonably priced and lots of color choices. I've seen 20D and 30D — does it matter which?
My issue is the lining. I don't particularly like the feel of the nylon ripstop. I don't think I like Momentum either. (It feels "plastic'y" to me…) Any pros/cons for using polyester fabrics? Are there lightweight downproof polyester fabrics available that I can use? I've also seen silk mentioned and I think that would be ideal. Are there special sources for down-proof silks or are most fine silks down-proof?
I'm aiming for less than a pound. I'm relatively small (5'2" woman, 135lb) so I think 8-9 oz of 800 or 900-fill down would be sufficient. I'd like it good to about 40-degrees.
Any other hints would be great — I've read through quite a few of the threads here about making quilts/working with down and I'm decent on the sewing machine. I've made a few silnylon tarps, pack covers, stuff-sacks, etc.
