Hi all! New here so very much finding my way around, apologies upfront if this is a daft question. My problem is finding the Product Attributes option when creating a listing. I make themed sets of charms that I'd like to sell in their different sizes but struggling at the moment. Is this feature only available in certain categories or do you need to do something to make it appear eg. add more images?

Catagory I'm trying to list in is Subcategory : 200548291
Crafts, Hanmade & Sewing > Beads & Jewellery Making : Charms & Pendants

Any advice much appreciated thanks xx
