I still experience a sense of shock every time I tally up what the materials alone cost for making a quilt. And then when I add in having it LA quilted - well, let's just say good quilting is not easily a for profit art form. Not unless you are a sweatshop owner somewhere in China.
Nancy don't feel awkward or bad for your friend. Since you didn't charge for your work, I'm assuming you made her the quilt out of love. She got an incredible bargain. I'm sure she realizes this by now. Maybe if you take her along sometime fabric shopping she will realize it even more.
Can't wait to see your quilt when it comes back from being longarmed!
