If you don't mind making the quilts, call her back and tell her that you need her to go pick out and purchase the fabric and tell her how much to get and also the batting. Specify how much of each and tell her you don't mind to do it once she has the fabric. If you don't want it to seem like you're saying you need to pay. Just call and say I've been thinking, and I need you to go and pick out the fabrics needed and also get the batting for the quilts. Or something similar. But like Ellen said, once you do one small thing for a family member it seems they try to take advantage of you b/c you are family...not always but most of the time. Believe me, I know this from experience with my aunt...grr.
