I love my EQ and use it all the time. it depends on if you want to design your own quilts. I play on mine all the time. I also use it to put ideas on it for later. When I see something i want to go back to I recreate it on my EQ so I can find it later and explore the possibilities.
You can import pictures and designs right into your EQ and use them in a quilt. I love to change colors and see what different looks I can get. You can import your own fabrics into EQ and then use them in your quilt design so you can see waht it would look like before you use the fabric.
If you'd like to see what it looks like you can see my free tutorials here -
