I have a plastic water bottle cap hanging in front of my archery target for a point of concentration.
I haven't been able to find white ones for quite some time.
So i was thinking, what else could I use that's cheap?
Wonder if I could find white beads or something.
Was in a department store going to look for something and I went past a golf display. 
There they were, whiffle balls the size of golf balls. 
And 12 for just under $4.
PERFECT. 

"AIM small, hit small "

Great idea!  Thanks for sharing.

I do think, if a field point finds one of those small holes, it could be time to replace the ball. 

Suspicion confirmed.

Finally got the picture to post.
