I've been seeing people do some picture transfers lately, and decided to try one of my own. First, I printed off a picture with a whole bunch of butterflies on it. I decided to go with a picture without people, just for my trial run. I printed it on regular paper.
Next, I applied gel medium to the wood I had chosen for this project. After the wood was completely covered, I placed the printed photo, face down, onto the wood, and set it aside to dry overnight (or close to 24 hours). (I did the first part at about 9pm, and then, after returning from work the next day, at approximately 5pm, I commenced the second stage.)
After everything was dry, I took a sponge and wet the paper on the wood, then rubbed with my fingers to remove all the paper (SUGGESTION: You may want to use rubber gloves! My fingers were so ink-stained, that I went to work the next day with purple hands!). When all the paper is off, let dry again.
My final steps were to add two coats of ModPodge (allow to dry between each), to seal in the ink and make it glossy or matte (whichever you choose). I really like how they turned out. I also ended up using some acrylic paint to spice up the edges with some color, before hanging, but you can do whatever suits your tastes! I've even seen this done on canvas, but I have as of yet to try it! ~Hoppy Crafting!
