Just ran across the following piece of information that I *know* I will forget, courtesy of Scarlet Quince News for March 2014:
"DMC Merged Colors
"In 2005, DMC 'merged' some of their color numbers in Europe. Changes in their dye formulas caused by evolving regulations and restrictions on chemicals used in dying meant that 7 pairs of colors had become so close together as to be indistinguishable. For each pair of colors, they discontinued one of the numbers and printed both numbers on the label of the other. Up until now, all 14 separate color numbers have been available in the US, but now the new labeling is going into effect in the US. Here are the colors in question:
"Example of new DMC labeling for merged colors Here is an example of the new labeling" [newsletter has an image of the label. Discontinued color is in parenthesis under the other color number.]
"At the moment, you may find 504 in the 504 bin, and both 3813 and 3813 (504) in the 3813 bin. If the stores are smart, they'll put some 3813 (504) in the 504 bin when all the old 504 is gone, but you may want to print this list and keep it in your wallet. We question how well the news will trickle down from DMC to local craft shops."
I know I'm gonna forget this and go crazy looking for a color that no longer exists when working an older pattern. Here's hoping I remember to look here.
