I love mod podge!
STEP 1 - Find an old window. STEP 2 - Clean STEP 3 - put some kind of sealer on the flaking paint. I used mod podge. STEP 4 - add fabric or paper to the back side of window. I used paper and mod podge for this step also. STEP 5 - find some creative thought, either cut it yourself with a cricut or buy it at a craft store. STEP 6 - hang on your wall and ENJOY!
