Guest helps
I hang an over the door shoe organizer on the back of the door of our guest room. In each of the different clear pockets I may include the following: a map of the local area, sun lotion, soaps and shampoos (usually the free hotel ones or samples), note cards, a good paper back book (with a note saying to take it with them if they haven't finished), candies, a flash light, a variety of medications and personal items, a couple of stamps, postcards from the surrounding area, etc. My guests seem to really appreciate it. And it's amazing how many of these little things are free or very inexpensive.
Storage for Gift Wrap
I hoard gift wrap especially after the holidays. Instead of investing in the underbed storage containers that cost around $15, I decided to ask a nearby flower shop for the shipping boxes for long stem roses. The boxes are the perfect length and you are recycling the boxes that usually get broken down.
Untangled Christmas Lights
I save the bread bag ties and use them to wrap up my Christmas lights. After they come off the tree, wrap them around your arm as you would an extension cord and then twist the ties around the bundle in at least 4 places. They store very nicely and next year you won't have to untangle them.
Makeup Storage Made Easy
Plastic silverware trays make great organizers for bathroom drawers, which tend to be narrow. Makeup, cotton balls, Q-tips and other supplies fit neatly in the silverware slots, and the trays can usually be found at garage sales for .25 cents or less.
I am adding this one in because, One, it's a good idea, and Two, HOMEMADE TOOTHPASTE?!
Glass Jars
Instead of throwing away those empty glass mayo and salad dressing jars (among other types of glass jars with screw top lids...), reuse them to store everything from buttons to cotton balls to beads and foreign coins. I reuse small jars with lids in my bathroom to hold my home made tooth-paste and other home made body care products. In the kitchen, old jars can hold wooden spoons, chopsticks, or dry beans. Anything is possible, just use your imagination.
Melt some spearmint gum and put it in a jar 
LOL! All that time you save being organized can be put to use making things like toothpaste, I guess.
Great ideas!
