Feedly Factory you can design your own Feedly button through an easy three-step process:
- Select your button design
- Load your feed URL
- Copy your HTML
The web page will create the HTML to place the button on your blog based on your input. You will then cut and paste this code as a gadget in Blogger. Be sure to post your feed URL, not just your blog's URL address. For help determining your feed URL, see here. (Thank you to Elizabeth for pointing this out!)
To add the Feedly button in Blogger, visit the layout page for your blog and locate the "add a gadget" link. Both circled in black below, though it's placement will vary based on the template used for your particular blog.
This will open the Add a Gadget link.
Scroll down the options until you find the HTML/Java Script gadget.
Cut and paste the provided HTML from the Feedly Factory page and press save.
The Title button will include a type-written title for your button, as shown below. I chose to leave this blank because the button speaks for itself.
Play around with the button size and design until you find the right look for your blog. Don't forget to save before exiting.
UPDATE: Blogger has a site listing it's feed URLs here.
