What are Dye Lot Variations?
Dye lot variations are slight differences in color between production runs of the same style of item. Dye lots are batches of textiles or fibers that are dyed in the same vat at the same time. No two batches of yarn are exactly the same. Even lots that are done right after the other will have slight differences in the final color. Yarn is much the same way. If the yarn base is different (from a different sheep, processed slightly differently) you will get different color results even in the same dyeing process.
