Great job, Jan!! They look like a perfect fit.
Welcome to the addiction :-)
I too have a sensitivity to wool but can wear it in socks. Go figure?!
Fixation is a cotton/nylon blend and Elann has Esprit that is basically the same thing. There is also Crystal Palace Panda Cotton, Katia Mississippi that is also cotton and sometimes I use Senso crochet yarn (cotton/microfiber) that you can pick up at Hobby Lobby.
