It's also a brilliant way of using up all your scraps of fabric. As any textile artist, sewer, maker or crafter knows, it goes against the grain to throw away any offcuts of fabric from a project, however small. This of course results in burgeoning shelves and bags full of scraps but you never know when these itty bitty scraps will come in handy as the last thing you want to do is cut into a virginal fat quarter just for a tiny scrap of fabric. Thus reverse applique, in fact any kind of applique is the ideal scrap buster.
Above is a picture of Louise Baldwin's quilt shown in detail.
For my version I kept the shapes similarly abstract and by layering many scraps of fabric onto a calico base this allowed me to cut back and expose the many various coloured fabrics underneath. I then used a teasel brush to fray the raw edges even more.
