Ok, here's how to change colors. Do the stitch you're working on half way. That means leave the last two loops on the hook. Get the color you want to go next. Wrap the new color around the hook and pull it through. Oh! You have to cut the old yarn first, leaving about an inch to crochet over. Now just crochet over the ends with the new color. Practice changing colors.
I'll post the first pattern next. I bet you're exited! I know I am!
