Just make sure not to add a bottle of whiskey to the costume unless you’re legal. You can request talented artists to make costumes for you. These will act as our “registration marks.” Make sure each registration mark is nice and thick, about 1/8″ to 1/4″ at least. Some had spent hours, days, or weeks on their costume while others turned up for the fun day out and to put on the free Sonic the Hedgehog hats that were being given out.
