What do you do with craft project rejects?

What do you do with those craft projects that ended up looking like they were made by a five year-old in the dark?

I recently took up crochet and I’m really enjoying it. Problem is, the “scarf” (quotation marks very appropriate) I’m working on is horrible. It’s not even wearable.

I’m not sure what to do with it once I’m done. Some sort of repurposing is in order until I can crochet something that doesn’t vaguely resemble Cthulhu.

Have you ever had a craft project that once completed, however poorly, you found a different use for? What was it? How did you come up with the idea?
