Yarn is dyed in lots and packed in cartons by dye lot. When a dye lot is shipped out, it will be shipped to a specific store somewhere in the country and before long that dye lot will be sold out. It is virtually never the case that we have a dye lot in our warehouse that you found in a store. For this reason, we write a statement on every yarn label that you should purchase whatever you need of a dye lot at one time.
