I have the EQ6 ... a friend has EQ4. We both think it was well worth it.
For me it is easier than using colored pencils and graph paper. I can scan in my fabrics or use what I find in EQ to see what the colors I want will look like. I even had programmed in a quilt I was teaching so those beginning quilters could see how changing color does change the quilt.
You can change a layout from regular to on pointe and more.
You can figure out what size you want to make and how to go about that.
Yes, I'd love to update my EQ ... but right now isn't the time for me to do that.
