I have started to make a rag rug. I am using an old coffee sack as the base and am raiding my fabric scrap bags. I use a small metal crochet hook to poke the fabric through the coffee sack. I am really enjoying the slightly mindless repetition of the project, very therapeutic!
2/5/12 Update: progress is going well on the rag rug. I still think it will take months but it really is the perfect hobby for anyone who has to always be making something whilst watching tv!
