|this is the best way that i know to create a secure knot in a length of hand sewing thread. if you are right handed, hold the threaded needle in your right hand and carefully wrap the very ends of your thread 3 or 4 times around the needle.(not too tight) next transfer the needle to your left hand and with your right hand holding the coiled thread, carefully slide the coil off the needle and down the thread length until you have reached the end and you have a nifty little knot. i usually trim the little tail that remains and then you are ready to sew. the knot is easiest to create before the thread is waxed or the use of " thread heaven ".
