Yes, I rarely purchase fabrics (other than what might be needed for filling in) for my charity quilts. However, I think this line of fabrics will be used by Linus blanketeers. Our chapter makes fabric postcards for thank you notes out of any fabric that has Linus on it, and this would be perfect! I can see chapters making banners or "poster quilts" out of the fabric for their presentations to groups.
In the past, when Project Linus has had a line of fabric designed for them, a small portion of the sales has been donated by the designer and/or manufacturer to the national headquarters of Project Linus. This sweetens the deal for quilters who want to support Linus even if they don't donate quilts. If some portion of this line's sales will be donated, then it is beneficial to have that fact noted at the store for potential buyers.
