So I have this idea bouncing around in my head and wanted to see what you other DIY'rs thought. I ordered some Insultex from BWDD and was thinking of a layered system.

From the Bottom

DownProof fabric of some type perhaps with some water repellence ability
Insultex 1 Layer
Down of some type salvaged from a Goodwill type store blanket
Downproof fabric of some type.

I am unsure of what pattern I will thread inject it together at this point.

Ideas? Comments?
