Since you have EQ7, you can do it. I did a SAS for myself for a quilt on our boat. I actually ended up paper piecing parts of it and then putting it together.
Fire up EQ and type in SAS in the search. You can make it any size or color/colors you want. Print out a picture of the quilt and then go to town coloring it. That is a great idea.
With EQ it will make it easier.
