Basically, cover canvas with a layer of mod podge, and carefully lay down tissue picture. I started in the middle and worked towards the edge pressing it down with my fingers.
Because I had the extra white spaces because life is more hectic than I like to discuss right now and I didn't do my measurements correctly.....I decided to take black paint and paint a ragged edge. If anyone ask, I shall call this artistic expression, and no procrastination/poor planning on my part. BUT, the bottom line is, in person, the tissue covered canvas looks awesome. I'm definitely doing this for various photos in my house, and future gifts for friends.
