A few years ago I began experimenting with making my own non-lethal projectiles using crochet. This turned out to be quite a challenge as I had never crocheted anything before, and there was much to learn. The first link is the conclusion of those experiments, the best pattern and closing technique. The second link takes you to a PDF that I used in my experiments compliments of Ms. Premise-Conclusion's Awesome Crochet Blog. Thank you Ms. Premise! The third link is a series of unorganized posts chronicling the search for the perfect non-lethal crocheted sling projectile.
