Hi! MJ here. I do change my thread color when piecing different facet colors, but you don't have to. If you use a medium value of the primary color of the gemstone, you'll be fine. I also used to change out my thread when piecing only because my old sewing machine was a grouchy old girl and we fought about tension all the time. I didn't like seeing Black thread marching up the seams of my white facets! Nore did I like seeing White thread marching up the seams of my black facets. That's resolved now that I'm using a BERNINA!
