I just finished my second penny ball. My two sister-in-laws were fighting over the last one so I decided to make another one so they each could have one. I actually made the first one as a joke as we found an old bowling ball in father's garage and they were going to pitch it. I told them that I would take it home and make it beautiful and bring it back at the next get- together. Everyone had a good laugh and loved the idea. So yes, anyone can make one of these. Find yourself a bowling ball either at a sale or at a bowling center ( ask them if they have any that are discarded or that are ruined) and get started. They look beautiful outside with the sun reflecting off them. If you need help, let me know.
