Cut the shape of the frames out of newspaper. So that you have the exact measurements and amount of pieces of paper as of the frames.
A little trick: If you have one really difficult size of frame, hang this first. I had this big picture frame that I just hung in a corner.
Now tape the newspaper to the wall and adjust and pull off and stick on again until you have a collage that’s nice on the eye. I let the paper hang over night and looked at it in the morning again. There’s no better quality control. I rearranged the paper again until I was fully satisfied.
Now hammer the nails right through the paper. No guessing or measuring necessary. You can rip off the paper afterwards. It did its job (perfectly).
Now hang the picture frames!
Your very own unique picture collage!
