|I wanted to save time while I was making my latest mini-wardrobe. Without actually buying 3 or 4 cones of thread to match each color of blue I would need for the project, I bought 3 cones of my most common color. Then, when I needed to stitch the seam with a different color thread, I just switched out my needle threads, leaving my loopers royal blue. I know it saved time and money.
(In the pic, you can ignore the white cone. I was only using 3 threads at the time.)
