Next Modge your images onto the dried backgrounds. If you don't want to paint just use other papers for your background, stamps or even alcohol inks but again I will not discuss those here. These are just other suggestions.
Make sure you have Modge on the back of the image and a bit on the surface of the domino as you don't want the image to lift. Smooth out image and make sure you have no bubbles are wrinkles. If the image is a bit oversized on the edges do not trim yet!!!!!! Allow the modge to dry or you will tear the damp paper in the process. Believe me when I say this!!! I am no Queen of Patience. I put a light layer of Modge on the image itself to make sure it was well adhered.
Let dry completely.
