Not sure where the opening is to the closet, but 4 feet is too quite narrow if it is accessed from one end.

Ribbons -- here's an example of what I would suggest. Since it is so narrow, put your closet shelving on one long wall and leave the other one free for just space. Attach your jewelry bling board (love that!) to the far short wall.
We offer all-hardwood shelving systems and kits that can be installed to meet almost every need. Let me know if you would like anymore information! www.copeclosetconcepts.com

Sorry ... image didn't attach the first time. Here it is.

Could give you a better answer if you could sketch the floor plan and show the door location, the width of the door, and the door swing or slide.
