This flower is made with size 15 beads and 30 gauge wire.
The pattern called for 30 gauge wire, but even with size 15 beads, the flower is a bit floppy. If I make another, I'll try 28 gauge. Hopefully, the two passes of wire will still fit through the size 15s.
Beaded flowers are a good way to use up extra beads from previous projects. I used the pattern in a past issue of Martha Stewart Weddings, but it's also available in her Encyclopedia of Crafts and on her website. I would only use the website version if you are familiar with making French beaded flowers, as it does not offer as many photos of the steps.
