Just because you posted and asked I think part of you is already thinking it might not be a good idea. Alsoyou have not seen the fabric so it is kind of like getting a cat in a bag. Most likely if she tried to sell the fabric she would have a hard time selling it at all. I agree, let her sell the fabric and pay you a fair price for making a quilt. this way you can buy fabric you like for sure in the quantities you need.
