I made this little shamrock in about 30 minutes, even with Anna distractions and learning the pattern. I'm learning more and more to like the thread crochet, because you can make a little project so quickly. I still have the "too big" problem though. For this I used a smaller hook than recommended, but it still came out much more loose than the one pictured.
Here's the pattern I used.
I'm not sure what I'm going to do with it, I thought about putting a pin on the back, but I'm not quite sure how to do that. It would also be cute as an applique on a bag or sweater or something.
Happy St. Patrick's Day!
