Yeah, most of my friends, when they found out I knitted, suggested I should perhaps go make friends with their grandmothers... (though not quite as nicely as that :mad:)
I told them not to come crying to me when Armageddon comes and they don't have anything to wear.
Honestly, I haven't tried dishcloths yet. I've done some potholders and trivets, but beyond that I've been working on an afghan, and now socks. Seems to me that knitted things would be great for scrubbing, though.
