Here is a pair of wool sweater longies I made for Trin out of a recycled wool sweater. Usually wool covers are made to be used as diaper covers. Since wool is naturally antibacterial and can absorb up to 30% of it's weight in wetness. You only have to wash it once a month or so (depending on it's usage). When I sold all my diapers I sold my wool covers as well. I made this one to go over Trin's training pants at night in case of any overflows. This way her bedding can stay dry.
