Need a trick for fingermark

Hello everybody,

I'm new in the world of papercraft and I'm actually working on the pepakura Finn from Adventure Time.

To do it, I use white glue. It works perfectly but my problem is that I have glue on my fingers and I leave fingermarks on the paper.

Do you have any trick to avoid the glue fingermarks ?

Thanks in advance

Paul

P.S : sorry for the bad english :/
