I'm not sure if it's to late, but we have reordered our Peruvian Highalnd Wool. One of the colors we hope to get is #0404 Charcoal Heather.
May I suggest that you tick off the "Email me if stock levels increase." button found on the product page for this yarn. This way when the yarn is again ready for sale you will be among the first to know.
All the best,
