Well I did and it was no easy feat since the wall I wanted it on was up on my double vaulted ceilings. Thank goodness for my awesome husband and his precise measurement talent!
I bought the biggest clock hands I could find which were about 17 3/4". I also had my vinyl custom made so I could make a huge clock. Since this clock was going up so high, I didn't want to use glass frames. I pictured having an earthquake, it happens, I live in California, and the frames falling and breaking on people. Not a pretty site even in my mind. So I used photo mount spray adhesive and foam board. I attached the pictures on the foam board first then we let it dry. After drying, we used an exacto knife and cut the pictures out. Then I hot glued a "claw" picture mounting device on the backside.
This is a great idea when you want to fill a giant space on your wall. And you get to personalize it with pictures of the ones you love!
