I have EQ6 and have played around with it a little. I did take the EQ6 class from Quilt University a couple of years ago, but couldn't keep up because work kept interfering. Now that I've retired, I'm wanting to learn it and maybe eventually upgrade to EQ7. Right now I have the manual right here next to the computer, so I need to practice!
One thing I really want to do is download fabrics from manufacturers, but haven't figured out how to do that. One of these days!
