It started out as a design I made in Photoshop of the pepper and the bowl against a cream background, with the whole against another larger pink background.
Then I uploaded the design to Society6 to sell, and the size worked nicely on the tote bag. Society6 take care of the printing and the delivery, and I get a cut of the difference between the selling price and their costs.
If you are interested in it, click the image and it will take you to Society6.
Next, coming up when I feel happy with it, is a long, long post on the pros and cons of different ways of selling online – Etsy, Shopify, etc.
