Invert any image with words and run your sheet through your printer. Print directly on the tissue paper. I just have a regular cheapo printer y'all and it worked just fine. Lightly spray your image with aerosol hair spray. This will set the ink. Seriously.
While your hair spray is drying, grab a wooden circle and get to painting. I used a glaze on my ornament. It goes on nice and thin allowing some of the wood grain to show through. Again allow to dry. NOTE: I painted both sides of my ornament.
Remove your tissue paper from your card stock. It is easier to just cut it then try to remove all of that tape. Apply a coat of Mod Podge to the ornament and lay your image down on top of that. Smooth from the center out using your fingers or a brush. Allow to dry.
