I have had EQ since version 4 - I use EQ7 for one reason or another on every quilt I make. Some times just to estimate the amount of fabric - or if I already have enough fabric for a particular layout. It does have a learning curve but it's fun learning too. Nowhere else can you experiment with multiple block/quilt sizes without actually cutting into your precious stash. Some days I spend more time with a "computer quilt" than the real thing but I'm always learning.
