Using Windows Paint or Linux GIMP or whatever software you are most familiar with, create a JPG graphic of the label you wish to use. Feel free to make it larger than that eventually desired, but maintain the correct proportions or aspect ratio.

 Begin by creating a thick-line rectangle around the outside perimeter of your label.

 Next insert a rounded corner rectangle, again from the graphics program toolbox, just inside -- and touching on all four sides of the square rectangle.

 Again from the graphics program toolbox, use the paintbrush or paint can to fill in the four empty triangles formed in the corners between the two rectangles.

 Light colored letters against a dark background work well, particularly on dark colored cabinets.

 Draw appropriately sized circles to mark the location of contols, LEDs or receptacles.

 Save the JPG graphic to your hard drive and then insert it into a blank document, perhaps using Microsoft WORD or you choice of word processing software.

  An optional, but helpful step is to superimpose the side and top ruler tool in your word processing application to faciliate the next step.

 Resize the graphic of your label to the desired size to fit your project cabinet but try to maintain the correct aspect ratio. You have a little leeway with this step, however, which helps to make the label fit precisely.

 Save, then print. How long did it take us to learn that lesson in the early days of highly-unstable computers. It still seems like a valid procedure though, doesn't it?

 Cover the label and some of the surrounding white paper around it with clear, wide label tape. Start from the middle and work out to the edges, being cautious to avoid trapping air into bubbles.

 Using sharp scissors, cut out your label along the outside demarkation of your heavy black rectangle border.

 Using a hole punch or sharp craft tools, cut out the holes marked for controls, LEDs, or receptacles.

 Now, with a black Sharpie marking pen or equivalent, go around the outside edge of the label. The black marker will fade right into the black ink of the rectangular border and hide the paper edge once the label is installed.

 Using double-sided tape or equivalent, fasten the label to the project cabinet.

 Insert your controls, LEDs or receptacles carefully through the label, cautiously securing them with the appropriate hardware using flat washers to avoid wrinkling the label when control nuts are tightened.

  Here are some examples of my early efforts.
I've seen others duplicate this process but end up with FAR more professional looking project labels. Your labels will be much better also. The two examples below show that the label tape chosen was not of the best quality and therefore not as clear as desired.
Note the inclusion of "hollow arrow" graphics on the second example. Your imagination is your only limitation.
