COATS MOON THREAD. Spun Polyester 120 thread. 1000yds ROYAL BLUE. A good quality budget thread made by Coats suitable for machine or hand sewing. Great for your overlocker too. This is a thread that I have used over many years profesional sewing so I can recomend it’s quality. Not as glossy as say Gutterman but it performs very well on all my machines.
