How to add an option for other color variations?

[ubetix]

Hello,

   I have tried to add a color variation to 3d printed deck boxes, but even after following all the tutorials (mainly for other products) and instructions found (by Google) I cannot find a way to add that on my listings. Any idea of how could I add multiple choices for customers to choose a color on a 3d printed deck box???

Thanks!

You cannot add variations to an existing listing.  You must create a new listing.  Not all categories allow for variations, so if you don't see the option, it isn't available.
