crazy idea...

[Raven Fyre]

So I have this crazy idea but I'm what I would still call a beginner knitter so here goes. I've made a soap bag (a bag you put a bar of soap in it foams it makes the soap pretty much last to the last drop) and clearly is machine washable. Well, since I like many other knitters am a female I don't use soap but rather body wash. So my question/idea, could a poof or shower flower or whatever everyone is calling the plastic fluffy things that are used for body wash be knitted? Any ideas how one would assmeble such a creature or what gage or anything would be groovey. The only thing I can think of is it probably needs to be a really small tiny set of needles like 0s or 1s or something.

Thanks in advance
