Sidebar Link

Hi!

I am using WordPress 3.0.1 and the Twenty Ten theme.

On every page of my website there is a link to the Home Page of my Blog and I would like to add a link to my website’s Home Page (NOT the Blog’s Home Page) on every sidebar of the Blog above Recent Posts.

I would like the link to look like this:

To return to

Home Page

image/link

with the above words.

How do I do it?

Thank you.
