DIY (part of our Save $) This is how I recommend to label the doors for us:
Write a number or letter that YOU WILL REMEMBER defining its location.
Example. (top left to right) A, B, C or 1, 2, 3 etc .
I will do the rest
Below is an example of what I do to "protect" your label so the spray doesn't overwrite (cover up) the label.
Tear off a strip of 2 inch painters tape about 6inch long
roll tape into a loop so it will stick to itself and the hole (like two way tape)
Push it securely into the hinge slot. Do this for each door. One label per door is fine.
