I really like this thread chart. I am able to select my thread for quilting based on actual thread instead of a dot of color on a card.
The newest Glide Thread Colors Card. (July, 2020) 245 colors. Actual thread samples. Card shows available prewound bobbin colors also. Card also includes Fil-tec's Glide 60wt, Affinity, and MagnaGlide Prewound Bobbin colors.
