By hand and with a sewing machine, this technique has so many possibilities. Imagination is the only limit! We can make really unusual stuffs using small and bigger pieces of very different materials. It is very interesting method, quite like embroidery but a lot faster.
I don't use patterns, if very seldom, so every bag is unique.
In the picture is my personal bag at the moment, which now is over a year old and still looks like brand new.
