Changing Purpose

I always start projects with a purpose, no matter how simple.  I wanted to make a scarf for one of my little buddies and I wanted to try out a new tunisian stitch.  I love the colors.  I love the patterns, but I'm not sure it's a scarf.

Do all crocheters stick to a purpose? Do your projects ever change course?

At the very least- this inspired an idea for a blanket!
