I'm rather new to knitting, but I've got ideas.
First, I want to make plus size cloths that actually fit. That one will be much later as I become a better knitter.
Second, I want to make a scrubbie for dishes. I've seen flat ones, but I want a big round one or one thick like a sponge. I've seen some patterns that call for tulle so I think that will be my choice of material, but from there I'm still thinking. I'll let you know when I've come up with more. :)
