I have very recently installed my first ecommerce program and am in the process of setting up my online store which will sell Knitting yarns among other items. Of course most customers will need more than one skein/ball, but my one trial item shows only '1' with no way to increase the number required except to keep going back and adding to the cart. no one is going to do this if they need 20 balls for a project. What do I need to do please? Thanks, Bernard.
