Thrifty? on hand? k.i.s.s.method... what did you use?

I finally got out yesterday to work again on the Jewel Box and got to thinking about the K(eep) I(t) S(imple) S(weetheart)! method, or using what you have on hand, or just trying to save $$$ ... mostly about the materials or items used that aren't really building materials or RV components.....
So what did you come up with and how did you use it ?
Here's mine: (with gratitude to whoever came up with it first)
1 Bicycle inner tube under the door hinge
2 Power strip for my "electrical system"
3 Plastic kid's pencil box for my fuse box
and everyone knows now about the popular stainless steel bowl made into a sink...
