I got these great little water-proof PVC cards that have every knot you could ever need. They are a bit larger than Doug's card, but they seem like they will fit in a tin. I should note that my PSK is not your typical Altoids or tobacco tin. My PSK is an Adventure Medical Kit "Backcountry", stuffed with everything I will need in a survival situation. I am in the process of taking pictures of the kit, and will post the link to it ASAP. Anyway, here's the link to the knot tying cards: www.proknot.com<br><br>P.S. If you prefer, I could scan these cards, you could condense the images, then have them laminated to be water-proof.<br><br>Hope this helps,<br><br>John McIntire<br><br>
