Be sure to follow the directions on the batting for how to close to make the lines of quilting. I'm not familiar with that particular batting, but I have used some Pellon batts that were very nice. In the past I've been given batting to use with the longarm that I hated working with. One was thin in some places and somewhat thicker in others, and had almost a sticky feel to it. I hated even touching it. As far as the fabric goes, this might be an opportunity to teach the mother the differences in fabric quality. Some of JoAnn's fabric is very good, some is not. If she understands that the cheap (in terms of quality) fabric will not last as long or look as good, she may choose more wisely in the future.
