Set up a pattern kit once: which yarns it uses and how many balls each size needs. On the product page, shoppers choose a size and a colour for each part of the pattern, and the ball counts, kit total and weight update as they go. At checkout the kit becomes the actual yarns and pattern, so it shares stock with single balls and each order lists the kit's size and colours. Colours you add to a yarn appear in every kit that uses it.
