Thanks for all the suggestions.
I liked Simply Soft best of all the acrylics I found except Utopia, but after a while it started feeling slimy to me. Go figure.
I haven't tried Bernat. I will look for it.
In answer to Jan's question, all I know is that wool makes me itch. Big time. Is that a "sensitivity" or an "allergy"? But I will try Encore and alpaca and see what happens.
I don't like working with 100% cotton (though I like wearing it) but an acrylic/cotton blend is a good idea. So is an acrylic/poly blend. I'll look for both.
Has anybody tried Patons Canadiana? It is advertized as an acrylic worsted. I don't know anything about it.
