You can actually scan in your own fabrics or download pictures of fabrics for sale to see how the quilt will really look like. It is not hard to design your own blocks on it. I like the fact that you can rotate blocks once they are colored to select the way you want the quilt to look like. It also allows you to print off the fabric amounts needed and paper templates you will use. Personally I love it and I never had any of the other versions.
Yes I feel it is worth it.
