Here is a handy design for a knot reference! Waterproof plastic cards mean you can stash this little reference (just 2 1/4 x 3 1/2) on your boat and not worry about it getting wet! Six cards are attached together in corner with a brass grommet. 17 essential knots cover most any rope tying situation: Bowline, Square Knot, Water Knot, Rolling Hitch, Sheet Bend (Doubled Sheet Bend too), Trucker's Hitch, Mooring Hitch, Tautline Hitch, Clove Hitch, Buntline Hitch, Constrictor Knot, Double Fisherman's, Figure Eight Follow Through, Prusik, Butterfly Knot, Half Hitch and the Bowline on a Bight. Put a set of these PRO-KNOT cards in your river pack and you’ll be glad you did!

It's a great little item to have with you when you're out and about, especially if you're still learning knots and you may not remember them in the field as well as you'd like to! This is a fantastic product for doing so, and being constructed of waterproof plastic cards means that you can get them dirty, get them wet and really put them through the ringer without making them unreadable!
