I figured it out. It took me three tries to get the beginning ring the right size, but after that I didn't have too much trouble with the cluster. The hard part was writing out the pattern - yikes - and this was a really simple pattern. So, without further ado, here is the original next to try #1, try #2, and the successful try #3 with the pattern below. If you try it out, please let me know if anything is confusing or you have trouble with something as this is my first try at writing out a pattern.
THRIFT STORE CROCHET FLOWER

ch 4; *YO twice, insert hook into ring, YO and pull up a loop, YO and draw through 2 loops twice; repeat from *; YO and draw through all 3 loops.
*ch 6; CLUSTER; repeat from * 10 times; ch 6; join with slip st to top of beginning cluster. Finish off: 12 clusters and 12 6 chain spaces.
BTW - we are going out of town for my cousin's wedding, so I won't be around for a few days. Looks like the weather will be enjoyable - hope you all have a good weekend!
