I am terribly sorry that you have run out of yarn. Jamieson and Smith, the company in Scotland which imports the yarn, has repackaged the yarn since we originally test knit and packaged our sweater kit. They claimed the balls were the same yardage as the previous skeins, but we packaged an extra ball of each color in any case. Unfortunately, our provisions seem not to have been enough and I do apologize for that. It is unpleasant to say the least to run out of yarn so close to the completion of a project, particularly when presented to you as a kit. Please send me your shipping address, and I will get a ball of the black yarn right to you.
