Double fisherman's knot

I have been on a climbing course all day today and it continues all day tomorrow and then I have to do a three hour assessment in the next couple of weeks. I wasn't particularly looking forward to the course as climbing is not really my thing but I surprised myself with some of the things I achieved today such as being the first female to reach the top of a 9 metre wall, self rappelling and climbing a rope. We were taught a tonne of things including lots of knots such as the one in my blip. I brought this rope home so that I could practise this evening - what a saddo!
