Oh my, look what I found!

While sorting through stuff in the basement, I found this old stash of yarn! Purchased in Germany back in the late eighties, I think I was planning on making a rug out of it. But I didn't like how it was turning out, so it fell by the wayside. So now what? I can surely find some way to use it - it's beautiful wool! Navy, dark green, dark grey and beige. Any suggestions are welcome!
