I am planing on eventually making a DIY down underquilt and of course I will need down to make it.

I want a underquilt that can get me down to at least -20 without any problem. So I need to get a lot of down for it.

So what I have been doing lately is finding lots of down at places like Goodwill and the Salvation Army stores.

Some of the vests and jackets that I have been buying are packed nicely with down and my plan is to take them apart and use my shop vac with a filter bag inside to store all the down in untill I need it.

I was wondering if anyone else has done this?
