I just luurrrve my EQ7! I agree, check out the previous threads, you are not the first person to ask. And, you will get as many people who love it as hate it.
My favorite things - I can dream up any block, color it any way I want, set it on point or horizontally, completely mess around with it without wasting any fabric. I can audition all kinds of variations and fabrics virtually. I love to paper piece, so I like to draw and print complicated blocks. I like to get estimates of how much yardage a specific project will require. I can spot problems before they happen, as seen in previous threads on this board about how a quilt ended up with sections that, once sewn together, unfortunately looked like swastikas.
