Since I mentioned that I spent Saturday evening crocheting, I thought I'd show you the result!
This hat is easy-peasy. If you know how to chain stitch and half double crochet, you can do it! I just crocheted a rectangle with an initial chain length of about 45 stitches. The row length is the height of the hat, and the number of rows make up the width. Once you have enough rows to wrap around your head, use a big needle to sew the first and last rows together. Sew a running stitch around the top of the hat to gather it in, and you're almost done! The last thing I did was to make a little crocheted "button" to go on the top; a pom-pom would work, as well.
