The first step is to find a drawer of a height that you like. I used a dresser drawer and if you look inside you can see where I wore a circle in the paper liner from cutting my containers to size. Keep in mind that the instructions supplied here are for a small size container cut to 3 3/4" tall. Your drawer will more than likely be unique. You will have to adjust your pattern height throughout. Also, pick a drawer that is flat on the top of the side so you can hold the knife flush against it securely in order to get a smooth straight cut. I could not hold the knife, turn the canister, and take a picture at the same time, and there was nobody around to take the picture for me. Use a fresh blade. It give a better cut. And it is important to have a clean even cut so the lid will fit back on. Simply hold the blade flush against the top of the drawer edge and turn the container. Keep the top on while you are doing it because it keeps the container more stable.
