Thank you for your replies. I took a few pics on my phone, but they're awful. I'll take some more and post them in the morning when I have some light.
To answer a few questions, I bought the size needles that the label said to use on the yarn. It does seem like when I actually do make it work for a stitch or two and start to get excited, it slips off. I will try a different cast on and see if that helps, too.
