The Crochet is Finished

Over the weekend my crochet circle was finally the size of my pillow, but I was nearly out of yarn so instead of purchasing another skein of the yarn I decided to try to do a circular weaving on the other side of the pillow.

I'm not really sure how I want it to look and I'm considering purchasing some more yarn (which totally defeats the purpose of me switching to weaving) because my stash yarns aren't the colors I think I want. Do you have any weaving tips or suggestions?
