I do planned quilts. I've tried scrappy but was too chaotic for me. When I made the Baltimore Album quilt for my daughter's wedding, I specifically bought fabrics to match their room and that would go together. The closest to scrappy I've done is the butterfly quilt for my little girl using leftover fabrics from dresses I made for her. That's not to say I don't save my scraps - if it is more than 1/4 inch, I save it. Sometimes I use them, along with planned.
