So when a friend started giving me scraps of fabric from her curtain making business I kept a few. The stash grew and I soon had enough to cover the sofa. I made loose covers, one for the back and one for the seat. I used my overlocker and just sewed pieces together. Once a few were together to make a bigger piece I laid this against the sofa and made a pattern pretty much freehand. It has worked really well, and as you can see Indie like it too!
Part one: the back
Part two: the whole thing
