Protecting a signature
I was commissioned to make a pair of pieces that will be taken to a convention and be signed. Y'all have recommendations for what method to ask the author to use?
My thoughts were:
Sharpie. Good - easy to use. Clear marks. Bad - prone to accidental wiping off
Pebeo paint pen. good - if the signiture comes back home intact, I can bake it. Bad - the paint doesn't flow as nicely as I would like and the paint is delicate until baked. Plus, I could not attach the signiture area until after its baked.
If there is a power outlet, an engraving pen. Good - permanent. Bad - hard to use neatly. Requires electricity. Glass dust
HOWEVER - the client was wondering if there is something more stable than a sharpie but flows better than the pebeo paint pen that would allow the author to sign the full finished piece rather than something that needs attached later, even if he needs to put a sealant spray on it or something.
Thoughts?
