Guide 2 ... divide up your stuff

Now lets get on with sorting out what you have now ... divide up your items into the categories shown below:

Clothes that require a "long" (greater than 1000mmm drop) hanging space ... coats, dresses, long skirts, etc.
Clothes that require a "short" (less than 1000mm drop) hanging space ... jackets, trousers, shirts, blouses, skirts, etc.
Clothes that are better stored "folded" ... jumpers, sweatshirts, etc.
Clothes that are best stored in "drawers" ... underwear, socks, tights, handkerchiefs, etc.
Miscellaneous Items to store on "racks" ... belts, ties, shoes, etc.
Non clothes items to sit on "shelves" ... hats, books, photo albums, family papers, etc.

Measure the lengths of rails required for each option and note these details down somewhere - as they will provide the foundation of your design.
