Adhesive sheets for front panel design
Some years ago I have found a good and reliable way for front panel design using multiple adhesive foils. For materials of my choice, see below. It goes like this:
Use
inkscape or similar vector based drawing tool and your measurement tools of choice to design the front panel.
Print the panel on the plain paper. Cut the frame out. Check the printed outline with the original enclosure. Iterate until satisfied with your results.
Store the panel's outline into separate layer for later use.
Print the panel on opaque (non-transparent) adhesive foil of your choice.
Print the panel's outline onto transparent protective sheet. My preference is slightly structured surface finish, which hides the manufacturing imperfections. Your preference may vary.
Stick your panel to the surface
Preferred adhesive foils
My preferred items are Conrad's

clear 160µm sheet for inkjets #529672,
as well as white sheet for inkjets #529648.
UPDATE:
Recently, I have found some alternative and cheaper self adhesive laser printer sheets from Lomond. They are sold by Agem in Slovakia:
