17. Stacking crates for your plants to build a shelf
We already gave an example of how you can take IKEA crates and add hairpin legs earlier on this list to turn it into a fantastic console table. Buying several boxes and piling them on top of each other is all you need to do with this hack. These boxes provide a multi-layered shelving unit that does not require any assembly at all. Of course, if you prefer, you can opt to paint a darker wood stain on it. But the fact that the wood has slats ensures that sunshine will come in. This makes it suitable for keeping your plants in the house.
