I finally learned how to add a mini Etsy to blogspot.
You can see it on the right side below my profile,
and click on it to go to my on-line stop.
The rest of this blog is a brief how-to for Etsy people:
Go to Etsy. Sign in. Go to my Etsy.
(This would actually be your Etsy, don't hack into MY Etsy. :)
In the lower left corner click on mini Etsy.
Select your configuration of columns and rows.
I used 2 columns by x 75 pixel thumbnails.
(You might have to click a submit button here...)
The code is generated for you to copy.
Select the code, copy it.
Go to your blog.
Go to Customize.
Select the Page Elements tab.
Click Add a gadget.
A dialog box appears:
My on-line shop is the title I used.
Paste the content you copied from Etsy into the content box.
Press Save in the dialog box.
Position your gadget where you want it.
Press Save in the Page Elements page.
View your new blog with a mini Etsy.
