The MAGAM theme for October is "Opalescence - sew & shine". Opals being the birthstone for October.
This was an easy one for me ... the fire opal is far more appealing than the milky ones. I have my two Anne Adams pattens and this fabric. Thats' as close to fire opals as I have in my stash.
It also counts in my Vintagw Sewing Pattern Pledge, which I've kinda let slide all year. Oops
