The only 4 knots you need to know... maybe!

We're releasing this video from the Patreon site as with half the world at home getting cabin fever (hopefully that's the only fever) at least you can practice your knots... This isn't just how to tie a knot, it's what knot is best. And I don't mean really complicated knots for specific applications, I mean easy useful knots that can be used for several things aboard. I've got it down to 4 knots that should cope with most things, but I admit I'm not counting stopper knots... well they don't really qualify as knots do they?!
