In regards to Velcro, let me say this: I have found more ways to use this stuff, in the sport of bowling, than in any other activity that I've ever been involved with.
I carry Velcro in my bag to make sure certain items stay put, especially when traveling. I have used Velcro, both the fuzzy side and the abrasive side in my ball holes.
And now, a new way to use it....... on my bowling shoes! This stuff is great.
