From Merchant & Mills. Pure beeswax potted in a cool little box with a lid.
Beeswax is traditionally used by tailors to strengthen thread when hand sewing buttonholes. Keep it by the sewing machine and pull your thread across it a couple of times before snipping off the thread end and it will be as easy as pie to get the stiff neat end through the machine needle. Marcy says, 'I use this for all hand stitching and is invaluable for sewing on buttons. Thread the needle, run the thread through the wax, then press the thread with a warm iron and the thread will not tangle.'
