Homemade kitchen organization

I am planning ways to make the best use of space  in our new place.  Here are some ideas I have:

Plastic bottle plastic bag storage

Magazine rack for storing cans

Towel bar for storing pot lids

using the inside of the cupboard doors for storing cling wrap and sandwich bags

cabinet handles on the inside of cupboard doors or the side of cabinets for storage

So what cool and interesting ideas do you have for making the best use of space, especially in the kitchen.
