Adding a variation

Hi all,

I am thinking about adding variations to some of my listings, it is my understanding that I cannot add variations to already active listings, so figure that my best bet is to create a new listing with variations that link to the other active listings that I have.

Sorry if it doesn’t really make sense, it barely makes sense to me. Logically we should just be able to link variations of our products from already active products. Also, our earrings are all fulfilled by FBA, just wondering if this would affect stock held in warehouses?

We sell earrings and jewellery so we would like to add different colour variations to the listing to promote upselling hopefully.

Thanks in advance for your time and help, I greatly appreciate it.
