Thanks to Ruth Wesolowski for this Frugal Baby Tip!
I switched to cloth diapers several months ago, and intended to make myself some "wet bags" to use as diaper pails. Well, turns out, I made one and don't like it (too small, takes too long to dry...) so what I have been using instead is just plastic grocery bags. They work great!
I double them up (one inside the other) and I put used (wet and poopy) dipes in "inner" bag, and soiled covers go in the "outer" bag (covers are sandwiched by the bags). It doesn't hold a ton, but by the time it's stuffed, it's time to do laundry anyhow. I just throw the used bags away. This really helps me get use out of all those bags!! And I don't have to spend money that I don't have on wet bags!
