It's actually Holly leaves with white berries, but everyone calls this mistletoe these days. ;)
This is tricky because the leaves have to be embroidered, and then sewn inside-out. Getting them right-side out and finishing the sewing is the harder bit; the satin tends to unravel even after you've managed to pin it together (which takes about 15 minutes... it's ridiculous, working with satin. :-P).
I will never make one of these again. xD The project itself was just too touchy!!!
