Our Dog died recently and we wanted to dedicate a keepsake shadow box to things like her collar, and her favorite things like her tennis ball, we placed a picture of her in it and placed it on the wall of our staircase to remember her daily. I had to cut the tennis ball to make it fit in the shadow box and everything was tacked down with pins that that when it was hung up it wouldn’t move. My kids decorated the wood letters, they just painted them white and used a sharpie to outline the letters in pink.
