Pattern: "Blooming Lace" by Melinda Miller.
I left off the last two rounds of this pattern to get it to measure 12", but then again, I used an I sized hook, which is one size up from the hook required in the pattern. I couldn't find my H hook! Oh no! Anyway, I finished the square and felt like there was something missing. I added the light blue slip stitch detail between the petals and the center of the flower, and now I think it looks just fine. The white petals looked a little skimpy, so instead of making them up of three treble crochet stitches, I worked the clusters up with five stitches.
