Step 2: Tape and make the first cut
The next thing you need to do is wrap the masking tape around the ends of the wood. Then when you are making the cut with your band saw it will stay together.
As you make your first cut down the length of your piece begin to curve the cut. You can make as many curves as you feel comfortable making. It does get to be a little tight though if you're trying to fit more than two bends within a foot.
