Here's a fun and easy project that I made a while back and wanted to share with you! I apologize for the lack of pictures, but I'll try to explain it as well as I can without them!
To begin with my clock looked something like this...
I took the clock apart and removed the circle part that had all the numbers on it in order to trace and cut out my scrapbook paper. I decided to just cut out 12, 3, 6, and 9 - and used flowers for all the numbers in between! I wanted to make sure everything was in the right spot, so I used a push pin to push holes through to the scrapbook paper (my new background) where each number was located on the original clock background.
So, I put it back together, and TA-DA - a beautiful clock for practically NO ADDITIONAL COST! :)
