Okay, I looked at the patterns and the numbers are definitely NOT DMC. I'm not actually sure what company the floss is associated with. To be honest, they are all projects that I have completed over the past ten years and the only things left are the patterns.
I can tell you that the patterns have color names (ie, light pink, medium green...) and there is a color photo for each in the respective bags that coordinate with the patterns. I have them separated so they won't get mixed up.
