Printing Tips:

• Make sure you preview your mask before printing. It takes a few minutes more but you'll be sure it is all with in printing borders.
• Use thick paper. Obviously in order for your mask to hold on through the scary night use cardboard paper.
• Full color is better than draft mode. Don't try to save ink because the effect will not be the same. If you are taking the time to make your own mask, print it full color all the way.
• Adding contact paper after printing before adding the strings will make your mask stronger and why not water proof, who knows what might happen during the night, trick or treating can get wet sometimes.
