A few months ago I was shopping at the mall when I passed the Armani Exchange window display and was completely awestruck. They were hanging jeans from their belt loop using a carabiner attached to polypropylene webbing. I liked the idea so much both for its aesthetics and functionality that I decided to make it when I got the chance (Bs/PhD program in Mechanical Engineering = very little free time). I regret not taking a picture of the display; however, somebody else on the web took a similar picture on Rodeo Ave. NOTE:This is entirely functional, not to display my jeans. This saves lots of time because I don't have to match up inseams and hang on a hanger. Also, other things can be hung from the carabiner as well (backpack, jacket, etc).
The materials for this instructable are easily attainable and cost little.
The polypropylene webbing can be purchased here. I used the 1.5" webbing for this project and purchased 11' in case I wanted to make another later. Cost of webbing (including shipping) was only $4.94 USD ($0.22 per foot + S&H)
I purchased my carabiner from EMS (Eastern Mountain Sports) for $6.45 USD (student discount). I could have opted for a cheaper one; however, I liked the colors of this carabiner and I felt as if this was the main part of the project. This is the carabiner I used, just in a different color.
Epoxy -- I had some lying around; therefore, I didn't have to purchase any.
