I stumbled into adding an Etsy mini to my blog! I owe it all to Timothy Adams' great information here http://critiquesandreviews.blogspot.com/search/label/How%20To%20Videos . It took a minute to figure out how to "add page element" because the screen did not look like his video. I clicked on "add widget" then on something like "link to third party site" or "add html code," and it worked! Obviously, I'm still a newbie since I had to cut and paste Timothy Adams' link.
