The next step is to create a new layer in the drawing for the Kitchen.
As with previous steps where new layers were added, the same process must be followed to create a layer for the kitchen.
First, open the sidebar.
Second, lock the Bathroom Fixtures layer since no additional changes will have to be made.
Fourth, as before, double click on the newly created layer (Layer 8) and rename it to Kitchen.
Lastly, make certain the Kitchen layer is selected and then dismiss the Layers Panel by clicking outside of it.
The Layers Panel will appear as shown below after the above changes have been made.
