Being well versed in knots beyond the simple granny knot is extremely handy, but if you don't use your knowledge of knot craft with regularity it's easy to forget. This handy card will help.
At Project Potpourri they were inspired by all the useful and diverse knots out there but were frustrated by how often they could have used a handy knot but couldn't recall how to do it. They created a basic card with knot diagrams on it. Once printed off and laminated, the card is a double sided guide to four common and useful knots on one side how to set up a basic tie down on the other. Tuck it in your wallet and never be left for want of a knot again. If you have a favourite resource for knot-tying knowledge and tricks, let's hear about it in the comments.
