Simply put, your piece together two or three pieces of the same fabric to create one large piece of fabric for your quilt back.
When I have done this I have actually kept it pretty simple and used two different navy blues split down the middle.
It’s a fun way to use leftover fabric, fat quarters, and other larger pieces of fabric.
You can do this with leftover blocks from other quilts or workshops, you can use a single stripe of fabric, or you can use a scrappy pieced stripe.
I use secondhand duvet covers for quilt backing quite a lot. It’s a simple way to get one large piece of fabric at a fraction of the cost of wide quilt backing fabric.
I use anti-pil fleece when I buy fleece fabric specifically for a quilt back. This is so you don’t get bits of fluff everywhere!
