I've used Mod Podge.

If it is plain paper, then mod podge. If it is something with an adhesive on it, like wallpaper, use an adhesive formulated for that type of paper.

Are you talking about Decoupage or putting a photo print on wood?

I've always used Mod Podge...which is decoupage gel. You can make your own or purchase the brand name. https://www.hometalk.com/3635368/make-your-own-mod-podge-much-cheaper-for-decor-and-craft-projects

Hello depending on the final result desired Iwould consider a glue stick, or Modpodge or-spray adhesive. Topcoat sealer might be necessary.

Hi Don, make sure your piece of wood is free of grime or any oily residue, and then use mod podge to glue the picture down.

Use Mod Podge

How is the piece of wood going to be used after the paper is glued on to it?
