Make Your Own Handles
This is arguably one of the easiest tips to implement, but you probably wouldn’t have thought about it in a million years. Do you know how difficult it is to lift cardboard boxes? They don’t come with built-in handles, but that doesn’t mean you can’t make your own.
What you can do is take a box cutter and cut a V shape into two opposite sides of a cardboard box. Then push the newly slit portion of the cardboard box inward to create two handles. Lifting heavy boxes is a lot easier with these DIY handles, but make sure you don’t overpack the box.
