This is how much fluffed wool came out of a box the size of the one that says “Tiny” on it, about a 1:3 ratio of unfluffed to fluffed (“Three bags full”!). However, when it gets installed, it gets packed in somewhat densely so that it won’t compress and leave a gap at the top. You want it so that you can stick your fingers into it but there is some resistance (as opposed to the compressed wool, which is hard to stick your fingers in, or the fluffed wool, which is totally loose.)
