Here's where a light touch is needed. With a serrated knife carefully and lightly slice the wafer cookie in half. My heels measured almost 2 1/2". Next you will slice the tip of the cut end at an angle. This is so the Milano cookie rests at the angled part. It's ok to not understand this until you see how the heel fits to the angle of the cookie. You may need to adjust the length by shaving the angled end down little by little.
