Here is what I would do. Make the Ten Minute Table runner using cheap fabric. Deliver it to her and have another table runner beautifully pieced, or appliqued, with quality fabrics in the same bag. Pull out the nicer one and say I have this to deliver after yours and then pull out her $12 one. You don't have to say anything but she'll be hit over the head with you get what you pay for.
