I use neutral colored cones almost exclusively for piecing and general sewing. I have a cone holder from Superior Threads. Previously, I had one of the cheap, metal holders and it was forever falling over. Because it is in almost constant use, it is worth the sale price I paid for it. I buy colored thread when I need colors. However, I buy the small spools. I think using the right thread is important. I have a large collection of types, sizes and colors. I especially like Superior threads such as King Tut for quilting.
