I like the design of this colour card which I continually refer to, helping me visualise future creations and the colour combinations. The colour card allows you to mix and match multiple colours at once to get a clear impression of the combinations.
The colour card is an essential item in my weaving tool box.
I was having trouble with the French naming on the Brassard 8/4 yarn. Names did not translate very well or not at all. I have found the colour cards with the thread attached to be very helpful.
