Brainstorming Product Lines to License Artwork

Essential oils and other aroma therapy products are fun. I love glass and metal along with the other natural materials.
Bath salt and other heath and wellbeing products would be nice.
I've wanted to make a set of tarot cards forever!
This is a set of cards done by an artist who I like a lot, Catalina Estrada
Clothes would be cool. I like these designs by http://www.bobmassevintage.com/
Wine and other specialty drinks could work.
Maybe custom decals for nails...
