What does slinging do to a sling ball?

Well it's not pretty.  Slinging your ballistic crochet will make it dirty, looser, and the stuffing will break and fall out a bit.  But after a dozen or so hard slings at a rough rock face target, this ball is holding together well.  So not to worry, you can always make more, and as they say, sling balls would be safe if you kept them in your pocket but that's not what slingballs were made for.
