There are 3 color versions proposed for this pattern :
Skeins required :

2 y : 2 skeins of Mineral (Ecru or Rocaille) = Contrast Color
3 skeins of Noir (Camel or Loden) = Main Color

4 y : 2 skeins of CC / 3 skeins of MC
6 y : 3 skeins of CC / 4 skeins of MC
8 y : 3 skeins of CC / 4 skeins of MC
10 y : 3 skeins of CC / 5 skeins of MC

In the pattern it is suggested to use DPN in order to avoid to break the yarn for color change
