Does anyone know if there is an app on the app store that can do this? Basically we sell Knitting Patterns and wanted to provide the option so customers can click if they want to buy the pattern and yarn together, they would then select their size and it would recommend how many balls of the specific yarn they need. Our competitor has something like this. Please see image attached. I've searched and searched but struggling to find something so thought it would be worth an ask here.
