After experimenting with Etsy as a store for my artworks, I have decided to move on. I have selected RedBubble, and my store is here.
The great advantage of RedBubble is that they allow me to offer a significantly wider range of products, from postcards to posters, at a range of prices. They take care of the printing and the shipping.
Please give the store a look. I have quite a few items already posted and I am preparing a lot more.
