If I can’t sleep in the next 30 days, then perhaps I’ll start folding.  On second thought, perhaps not.  I’ll just stick with the standard folded place card with a Swarovski hot-stick crystal ironed on it.  Ironing on the crystals onto the wedding invitations was surprisingly therapeutic and meditative!
