In this tutorial, we learn how to use a jigsaw. First, measure and mark the size of the circle you need to cut. You can use a compass or trace around a round object. Now, place your wood off of a table and clamp it into a place. Now, drill a starter hold inside the circle and put on your protective glasses. Now, place the saw in the starter hole and saw half way up, or to where you feel comfortable. After this, reposition yourself, then continue on. Make sure you don't force the saw, just let it go at its own pace. When finished, use sandpaper to sand the inside of the hole, then finished creating your project!
