I bought the two oak chairs for two pounds each from ebay (bargain!) and I've renovated the wood by sanding off the old varnish and waxing them. Of course I've also stripped back the chair seats and re-upholstered them (I've included pictures of the upholstery process this time).
Finally all thats left for me too do is screen or digitally print some of my fabric designs and add them as the top layer of fabric. Meanwhile I have created a photoshopped impression of what my chairs may look like when they have my designs on them. (Although I am not necessarily using the designs that I have shown in the picture).
