This soaker is knit from superwash wool and then dyed in black cherry Kool Aid. Soaker is another name for a wool diaper cover to be used with cloth diapers. The name is kind of gross and misleading as the whole idea is that the wool will be water/liquid resistant. I'm going to have to experiment with lanolinizing a few of these before I send them out.
On a personal note, I have never changed a diaper. This shocks some people, but I don't know many babies, and none well enough to fish through their frass. I'd like to keep it that way, so don't be driving to my house with a poopy baby so I can have a growth experience. OK? Good.
