The paired colorways are intended to work well for planned pooling projects. They specifically will work well with the Koi Pool shawl by Nim Teasdale.
With this combination, the ends will fade to red and the blue will be the contrast color in the motif.
The price listed is for one skein of each colorway. For the Koi Pool shawl at the recommended size you will need two skeins of each colorway.
