I like the Granny in it because it gives a warm feeling, almost everyone has a great experience with their granny. You certainly don't have to be very old to become a grandmother. Also I like to have quilt or quilting in the name, because it identifies the product.
Good luck, I think that is very quilters dream and it is great your husband is supportive. Be sure to set up a great web site, I buy most of my fabric on line.
