I need to second what edmos1 said...the plastic wrap on the sushi rolling mat is key. The other keys are to have a bowl of water for your fingers so that they don't stick to the rice as much. Also, a good asian knife like the ones from global (see
knife merchant - global knives ) is a great help. By the way, knifemerchant.com has the best prices that I have found on all knives...
