I've only ever had one friend offer me fabric. It was lovely. She'd planned to use it an old house, but moved before she ever got the chance. I used one coordinating solid fabric and made her a simple churn dash lap quilt as a thank you. Every time I go to her house, it's right in her main room, on display. I smile inside every time I see it.
Oh, and I probably had about 4 yards leftover after making her quilt!
