Rhonda here on QB created several tutorials on how to use EQ7. Check them out.

There are a lot more ... just search through tutorials now that you know what to look for.
I use EQ7 quite a bit for different things.
Just yesterday I saw the quilt that someone made 1 year late for a wedding (the same one QuiltnNan posted a link to) and I drew that out in EQ and saved it for a future date.
I have been making the Omigosh quilt but wanted a different block than the Shoo-Fly block - I wanted a different secondary pattern. So I drew up a bunch of different blocks and inserted them with the double-nine-patch blocks to audition secondary patterns that I liked.
I wanted to audition various pieced borders for a quilt that was made out of a center printed panel. So I took a picture of the panel then made that the "quilt block" in EQ and designed a border around it.
I quite often will sketch out a quilt quickly and just swap colors around to audition colors. I've even photographed some of my fabrics and uploaded them to EQ so I could audition with *my* fabric.
I will say that it is not intuitive at first ... it did take me a while to figure out what was what in the system, but I did get and I love using it now.
