Finally done! This took me forever due to gauge problems, but when I finally figured it out, it wasn't hard to make.
I made it in Jo Sharp DK Cotton in Carmen, and I found the yarn to be a little difficult to work with since it threaded apart easily (I don't recommend it, but it was $2/ball on clearance).
I'm not sure if I like the ribbon (and it's too wide, 1/2 inch, not 1/4 inch)--it's a cream color, which isn't bad with the red. The ribbon really helps to stabilze the collar. Sorry for the grainy pic, I really need to clean my mirror and fix my lighting.
