2 pack of needle threader with cutter to trim treads. How to use a thread cutter: 1) The needle threader consists of two parts. The handle & the wire. The end of the wire that is away from the holder is folded. Place the folded wire of the needle threader through the eye of the sewing needle. 2) Place the thread into the wire loop of the needle threader. 3) Holding on to the body of the needle threader, pull the wire part back through the eye of the needle, stopping when you have one thread in the eye of the needle. Remove the thread from the wire part of the needle threader. Knot your thread and sew.
