I tend to crochet afghans in the winter months. It keeps me warm in the evenings. We really needed a new afghan for our bed. I had a lot of left over yarns and several unfinished projects that were never going to get done. So I randomly put them together to make a huge afghan for my bed. My bed is a queen size, but I'm pretty sure this thing would fit a king size bed.
Now I'm working on one for the kids. Eventually I'll actually make something from a pattern again. Until then, it's fun seeing how scrap afghans turn out.
