This may have been the fastest knitting project I ever did. It's a wool soaker cloth diaper cover, though for now it will just be a pair of shorts for "Hero" bear. I knitted up the newborn size because I didn't know if I would have enough of my trash yarn to make a bigger one. Plus, I wanted to learn the pattern using the smallest size because then it's way faster. Less than one week! It's pretty cute, and it was really fun to knit. I learned a few new techniques on it.
If you're interested, here's the pattern.
