Skein: Yarn Kits by Size

Sell pattern kits by size: shoppers pick colours, and you sell the real yarn from your stock.

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.

• Show how many balls of each colour a size needs on the product page.
• Sell kits as your real yarn, sharing stock with single balls.
• Kits total the exact yarns chosen, so premium colours add to the kit.
• Add a colour to a yarn once and every kit using it offers it.
• See each kit order's size and colour per slot, ready to pack.
