Step #1 – You must first trace your hand, fingers together and thumb extended as in the picture.
Step #2 – Draw a straight line down from the top of each finger to the lowest point. On the sides, bring it down to the wrist. In between the fingers draw the line down to the point between fingers as illustrated in the picture. Don’t worry about cutting off some of the finger as I did by the pinky. You want the finger stall walls to be straight.
