We've been having wardrobe problems (well, lack of wardrobe hanging space!) for a while, and the final straw was storage for him indoors' evergrowing collection of jeans, which had outgrown the chest of drawers. I knew I had to do something.
The wardrobe is actually a cupboard over the stairs, so it's nice and high, with lots of shelving above head height, deep but not so wide. I decided on a re-fit, shop style, one rail above another. I also forgot to take 'before' photos. Use your imagination, the top rail was actually 8 inches lower than it is now (if you look carefully, you can see the old holes in the wall!), and the bottom of the wardrobe was a mass of coat hangers, slippers and bags.
Finished! New rail (lower one) is a sturdy piece of metal tubing found in mum's shed, lightly sanded and polished, the brackets cut from part of an old bed frame. Note the piece of wood on the wall, (again from an old bed frame, a slat this time) attached in two places and has cup hooks at regular intervals, for those bags that were littering the floor beforehand.
