With a thick and thin, somewhat chunky yarn, the simpler patterns - stockinette, seed, basket - look best. The texture comes from the yarn, a lacey pattern would get lost in it.
I jus saw somewhere on Knitting Help a double fabric in the round…this is driving me crazy…I am looking for it for you, but no luck so far…has anyone else seen it? It was either this morning or last night. Then I thought it might be on Knitty, but I did a search there and nothing…I swore I put it on my favorites too and it’s not there either…maybe I’m dreaming, but I will keep looking!
