Patchwork has been so popular for so many years and has been a special class of needle work for quilting and fashion. I once stumbled a Russian site showing a list of patchwork furniture which really catch eyes, so sad not to remember where it is. And now this patchwork furniture is floating around the media. We have some quilting projects with tutorials before that may help stitching the quilts, but if you want to re-upholstery your own furniture, chair or sofa, you may need to find some video tutorials and get hanging of it.

These sofa and couches are actually being sold for thousands of dollars at several high end boutique stores. But if you know the basics of how to re-upholster furniture in general. Then with some basic needling skills, you can design your own patterns and patchwork together your fabric first, and upholster your boutique-looking furniture on your own.
Here is a video of a general process of sofa patchwork, in Russian but good to guide us through on how it can be done, good luck there.
