I'm always baffled at finding silk liners priced around $40 or even more. Does anyone know of sites with a liner around or under $20? I find it hard to take the idea seriously of spending so much money for a piece of silk. I'd make one myself if I had a sewing machine, but I dont think that hand-stitching would be strong enough to sleep in. Perhaps there are other lightweight liner alternatives that are cheaper? I want something lightweight to use with my summer quilt when temps drop to around 40 degrees.
