It's the best thing since sliced bread! I taught myself how to use EQ by redrawing every purchased pattern I wanted to make, and I still do that today. If they made any errors in their pattern, I don't worry about it because I follow the duplicate I made in EQ. I design most of my quilts and just can't imagine doing so without EQ. I think it's around $250 MSRP, but you can get good sales on it.
