Knitting again!

So now that I have the basics of knitting and purling under my belt.. I decided I'd make a hat

all by myself... One row of knit, one row of purl into a rectangle. I reversed the rows at the top creating a row in which I could put a crochet chain. I crocheted the rectangle together, gathered the top and added a chain with two pom-poms.. and Whalah!   So easy.. no pattern and effective.. now can I make one for myself???
