I've braved stripping all the old material off and using this as a pattern to re-cover with tacks and a staple gun and dare I say it it's going really well and looks just as it did before but lovely as all the stained material has gone!!
I haven't done a re-upholstery course but have learnt just from dismantling the old covering what order to re-cover it in and it's addictive despite the hard work.
I guess this is quite a good thing given we couldn't afford to get a professional involved, and now my brother's asking if I can learn to make curtains too!!
