I teach two different BOMs at two different shops. Each person picks her own fabrics. Even with all the same fabrics, if there are 20 people in the class, just how many of those people are close enough friends that you're going to see your quilt in their homes? BOM is a learning experience. Learn the techniques and don't fret that someone else will have the same quilt. I've seen lots of quilts that I would love to make, and I don't worry that mine will be like someone else's.
