After seeing j626no's Instructable, I realized that a modification of this concept would work perfectly for my bedroom. I typically just leave my jeans draped over my dresser, and it looks pretty sloppy. A quick trip to the store and twenty minutes of labor produced results I'm quite happy with. I put together three of these, and it was about $15 for the parts. It's a very simple and straight-forward project, but I was happy with it and wanted to share :)
Step 1: Materials and Tools
Very simple list of materials. For each of these hangers, you're going to need:
(I used 2.5" Zinc L-Brackets, came in a package of 4. Make sure it has holes near the ends; I think that most do)
(Came in a package of 3, found one that would fit in the hole of the L-Bracket)
*One Length of Chain
(Since I was making three of these, I got chains in lengths of 1', 1.5', and 2')
*One Carabiner (or an additional S-Hook)
(They were only a buck each, and made it a lot more fun, but an S-Hook would work as well)
As far as tools, you'll need the following:
*Small Piece of Scrap Wood
It's important that at least one edge of the scrap wood is the same size or smaller than the thickness of your door, as you're going to use it to form the L-Bracket into its new and exciting shape.
Step 2: Measure Twice, Smash Once
We need to turn the L-Bracket into a U-Bracket. Place it on top of your door and mark across the bracket so you know where the bend needs to go. If it's easier, you can draw the line on the bottom and just sort of trace it around to the top.
You probably want to give yourself an extra 1/8" or so, since a bracket that's slightly too large will be fine, but one that's slightly too small isn't going to be any good.
Step 3: Clamp and Smash
Time to turn your L-Bracket into a U-Bracket. Take your piece of scrap wood (it's going to get a little dinged up by the time you're done), line up the mark you made in the previous step with the edge of the board, and clamp it down (first image). It helps if you get the clamp right on the edge of the wood. Once it's all lined up and clamped down, give it a few whacks with the hammer. Once it bends slightly, it's easier to turn the wood over so you're striking towards the wood, instead of into the air. Get it to a nice 90 degree angle (second image) and give it a test fitting over your door.
Once it fits the door, you're going to want to clamp the long end in order to give it another 90 degree bend. This is so that your S-Hook will have room to fit into the bracket without scraping up your door. You don't want to scrape up your door. I totally did not scrape up my door. When you're done, you should have turned your U-Bracket into, well, I don't know, maybe the Russians have a letter for it (third image).
Repeat this for each hanger you're going to make.
Step 4: Assemble and Hang
You've done the hard work, now you're in the home stretch. Place the S-Hook in the (Russian Letter)-Bracket, attach the chain to the S-Hook, and the Carabiner to the bottom of the chain. If you're making several of these, try getting different lengths of chain for a slightly more stylish look. Or, if you wanted, you could use webbing like the Instructable that inspired this one. You can get away with using an S-Hook for the bottom, but honestly, this whole project was just an excuse for me to buy some purple Carabiners, so just go for it :)
Step 5: Jeanification and Admiration
That's it! Just place your hangers over the top of the door, attach your jeans, and write up the Instructable. Well hey, looky there, I did that last step for you! Think of all the time you'll save.
Enjoy, and hopefully this inspires you to come up with some creative solution to a problem you might not even known you had. Or, at the very least, an excuse to go buy some purple Carabiners...
Step 6: Update!
Still using this setup every day and loving it! I've expanded my wardrobe, and all I had to do was go out and buy three more carabiners and put each one half way up the chain, and voila, double capacity :)
