There are limitless possibilities for using cardboard. This instructable shows many projects, short descriptions, included photos, mouth watering ideas, can't wait to get started prompts, where does the time go, I can't do it all, I LOVE cardboard , ad infinitum ways to envision it, design it, construct it, use it and how to enjoy the whole process! Build it, don't buy it! There are, of course many more ways to slice it (the cardboard) but I don't want to overdo it all at once.
I use cardboard to make storage of paint cans easier. Since there is little access to old paint, I put it down on the floor, under other shelving units. If I ever need a touch up, I simply pull out box with paint in it, and go to work.
Step 6: Waste Baskets
Step 7: Project Boxes
In order to semi-organize my work space and keep some semblance of order, I make project boxes that can be used to place works in progress. That way I can have several going at one time, yet know exactly where they are.
Step 8: Specially Designed Containers For Paper Flowers
I make paper flowers, and to store and or transport them, I needed to come up with a container that would enclose and protect the arrangements while in transit. Hence a specially cut and formed box.
Step 9: Shelving Unit(s)
Small units, but size could be expanded to larger sizes if needed.
Step 10: Tool Drawers For Work Bench
Drawers made of cardboard, to fit precisely under the workbench. This way, the whole space is utilized, and access is made easy by simply pulling out "drawer".
