If you are going to use it as a dishcloth- acrylic doesn't absorb water. wool will probably shrink / felt with washing. Cotton wahses well, absorbs H20, can be scrubby, andhows pretty stitches. If it is just for decoration it probably doesn't matter what it is made of. (I'd label it well if it is a gift...)
did I say one project at a time?
To be honest I dont think that I have ever heard of dishcloths being done in anything but cotton. One thing to be careful with when knitting a dish cloth is if there is a pattern like the one with a sailboat in the free pattern section her on KH a solid color works best. But of you do that garterlac disk cloth i think a verigated would look sweet.
i'm making artlady's basketweave dishcloths right now and i'm using microspun by lion brand to make them. it is microfiber, which is acrylic. now, i have not used them yet but i have used microfiber cloths in the past to clean and they work sooooo well. i love microfiber. they last much longer than cotton and look better also.
