I finished the moon using the Petite Treasure Braid as recommended by Jacqui - thanks so much for the suggestion!!! The colour didn't quite match the Kreinik colour, but I think it will do just fine. It was so easy to use, I loved it!
Now I'm just slacking, I can't seem to get motivated to finish and add the beads. My goal is still to finish before Halloween, guess I'll be busy this weekend!
