Keep a clear record of each batch you comb, card, blend, or prepare for spinning. This US Letter sheet tracks the fiber source, method and tools, dry input and prepared weights, noil or waste, yield, and what you want to make. A cut-out batch label at the bottom carries the same ID to your prepared fiber.

Print at actual size. Weigh dry fiber in the same units before and after preparation, then cut out the label if you want it to travel with the fiber. Find more on Fiber Arts Printables.
