EQ7 is good for creating quilt patterns, but I think it is not as friendly as it could be. Others love it. I have made several quilt patterns using blocks found in EQ7 and they've turned out well.
EQ also sells Quilt Design Wizard for about $30. It's more basic from what I have read, but I have never used it so can't say
So do a search on Quilting software and see what you find. Good luck and I am sure your Auntie is smiling down on you.
