I was inspired by the recent hot weather in southern California and Indiana Jones to make a collapsible hanger for my coat. It only takes 5 - 10 minutes to make one of these, fits easily in the bottom of a backpack for camping, and it is much sturdier than wire hangers.
Step 1: Supplies
All that is needed for this project is (per hanger):
About 3 feet of 1/2" PVC
4 feet of rope
1 old wire hanger
Step 2: Cut the PVC
Take your old hanger and measure out the lengths of the sides. Mark these lengths on your pipe and cut.
Step 3: Get the Hook
You can use just about any hook you want, but I used one from an old wire hanger. Cut about an inch bellow the end of the twisty base of the hook. Then take pliers and bend the remaining prongs up (see picture two).
Step 4: Tie it all Together
Take your length of rope and feed one end trough the PVC sections (make sure they are in the right order). Tie the two ends of the rope together to make a loop, but MAKE SURE to leave at least 6 inches of slack in the loop. If you don't it won't be able to collapse. Then hook the hook on the rope as show in picture 2. Use the pliers to crimp in the prongs to the base so they look like picture three.
Step 5: Stay Wrinkle Free
These hangers are just about as strong as store bought wooden hangers and should hold up for a good long time. Just make sure the hook is centered by re adjusting the rope every once and a while.
