To make a slip knot, hold the yarn so that the tail of the yarn ball is hanging in front of your hand.
Wrap the yarn loosely behind your first two fingers of your left hand. The yarn should loop all the way around your fingers clockwise.
Take the part of the yarn that's attached to the ball and slip it back under the loop behind your fingers (shown below without a hand involved).
Then slide this off your fingers, pull to tighten slightly, and slip it over the needle.
