I'm thinking of trying to design a brewery logo. Do you guys think that those window cling static decals would seal well enough against a carboy to use as a stencil for a design? (to then etch with the method described here)
Check out this site for what I mean:

You could print out your design, cut it out with an exacto knife (I'm not artistic, but I can probably trace...) and use it several times over on each item you want your logo on.
EDIT:
Oh and if you have carboys that are the same diameter you could make one big (or two because of 8.5 X 11 restraint) cling-ons to make the measurement marker as shown in the original post
