I make only scrappy quilts. Years ago, I fell in love with scrappy quilts like the ones my grandmother made. She was a purist as you would say--using only scraps.
I use my scraps but run out of them. I have cut up old cotton shirts and skirts. I also shop for new fabric. I cut from my stash as needed. I don't have a large space to sew nor do I have a large stash. Most of my stash is 1/2 yard or less fabric pieces.
