I've been wondering what to do for
labels in the cockpit of a homebuilt...

Here's what I generally do to get placards, checklists, and etcetera
that are lightweight, cheap, and durable:

I buy the clear sheets that you can laser or ink jet print on for
overhead slides. Then I use a graphics or word-processing program to
print the label or placard in reverse on the clear sheet. Next, I
apply contact paper of a color appropriate to the placard to the
printed side of the clear sheet. Finally, I apply spray glue such as
3M 77 or Super 90 to the contact paper side, wait until the glue is
tacky, and stick the placard in place.

The set of placards I made for my HP-11 sailplane about six years ago
was still in service last fall.

Thanks, and best regards to all
