Simplicity Pro Polyester Thread 40wt 1,100yds - Excellent for ALL Machines
This durable, high sheen genuine Brother Simplicity embroidery thread is made of 100% ultra-bright trilobal thread polyester, which retains its color, heat resistance, and strength. The 40-weight, 1,100 yard Mini King spools are single-snap cones to help keep your thread from unwinding. This thread is excellent for all machines.
Trilobal refers to the shape of the fibers that make up the thread. Standard poly fibers are round, but Trilobal fibers are like a three pointed star. This provides a lot more surface to reflect the light and result in thread that has a high sheen – often as much as rayon!
