I currently have the minimum 5 listed in my Etsy shop, come and see HERE
Also I have some past work to share, I will list them soon:
The great advantage of Etsy is the long time they are listed online, and after keeping some of mine for months and some of the years, I can tell you, the benefit of using quality paper and paint is that they look like I painted them yesterday.
I made a series of ACEO with water-mix oils on canvas, and I never listed them because I couldn't decide if I wanted to trim them to card size, or leave them with the edge I tape them to paint them, in case the buyer wanted to frame them. I guess I can put that in the listing, so they can decide what they want. I personally like them both ways.
What do you think?
