I have, and I loved it! I used it for a hoodie for my ds a few years ago - it was my first big project. I thought it was 100% acrylic but later noticed that it's an acrylic/cotton blend. It's really nice and soft and it washes up really well. Here's a pic....
(I think KellyK and Jan in CA have used it too, probably others as well)
