With more complex quilts, it’s helpful to turn layers off and on while you work on another layer.
At the bottom of the worktable, you’ll see yellow light bulbs on each layer tab. They are yellow because they are “on”, meaning they are all currently visible. Click the light bulb next to Layer 1. It will turn gray, meaning “off”, and the contents of layer 1 become very light. Click the other light bulbs on and off to see how useful this is.
