Was wondering if anyone has covered a bowling ball with these, with family pics. I want to make a memory ball. but don't know if I have to seal the pics onto each marble first Would appreciate any help.
That's a great idea for a BB. I'm no expert and someone else might correct me, but I would think you don't have to seal the pics to the marbles first, just use GE Silicone II to glue them to the BB, and then grout it. Would love to see the pic of the Memory BB after you're done.
