Waste Not, Want Not

Outgrown clothing is still useful. Rugs and blankets can be made from strips or squares of material and scarecrows can be outfitted with old, outgrown clothing.
Consider using cloth baby diapers instead of disposables. (More on this later.)
Getting back to basics means using every part of whatever it is you have. Waste not, want not is the motto of those who live off the land, and ultimately off the grid.
