Step-by-step explanation:
Yes, it is important to clearly mark all lines to be cut on a scroll saw. By marking the lines, you ensure accuracy and precision in your cutting. This is especially important when working on intricate designs or patterns.
One way to mark the lines is to use a pencil or marker to draw the cut lines directly on the material you are working with. This will serve as a guide for your cutting.
Another method is to use masking tape on the material. You can mark the cut lines on the tape, and then use a scroll saw to cut along those lines.
