Have you looked at your machine's manual? It should list and show designs of all the stitch patterns you can do on your machine.
I followed Carol Ann Waugh's suggestion of making a stitch bible. You go through all the stitches for your machine, switching the length and width of the stitch to see different variations. I love it and refer to it all the time.
Don't forget to use some kind of stabalizer to avoid puckering. Good luck!
