If one of the reasons for starting a blog is to advertise your online shop, it might be a good idea to add some images of items that your readers could buy. One way to do this is as a slideshow.
Log into your blog and click on 'layout' on the left hand menu. Click on 'add a gadget' and scroll down until you find one the slideshow one. Click the little plus icon and you will get this screen:
You can add a title that will show above your slideshow. How about something like 'available now in my folksy shop'. Choose 'other' as the source and then copy your shop url into the feed box. At the end add '.rss' to make it into a feed. And you might want to check 'open links in a new window' - this means that when they click on an item in the slideshow it takes them to that item in your shop in a new window rather than directing them away from your blog page.
Click on save. Back in the layout screen you can drag your new slideshow to wherever you want it. Then sit back and admire!
