That's flippin' adorable! I have always wanted to crochet something spontaneous... but I always seem to stick to the patterns! Now, seeing that someone else has done it with ease... I shall attempt to do that! CUTE!
Its not that hard. All you need to have is something you want to make, and a basic sense of single crochets, increases and decreases. I winged it. The best way it to just get in there and try something.
