This will be learning by trial and error. The vision is to provide a free platform for artists to offer their art in exchange for another artist's art. I am still not all that familiar with the details of how Blogger works. But here is how I see it functioning in the blogger format.
For now at least, email up to six paintings you are willing to trade, as 72 resolution jpegs. (See more instructions in right column) I will post it. If you see a painting posted for which you would like to trade yours, simply click the link to that painting.
So let's try it and see what happens. We can make changes along the way. Maybe at some point the blog can be made "open" so each artist posts his or her own work?
