While candles add warmth and light to every space, making your home feel cozier, they don't last forever and can be a little pricey. However, you can make them yourself really easily with a few supplies and a little bit of know-how. As a bonus, you can control what goes into them. If you're sensitive to fragrance, leave it out. If you're concerned about keeping the air in your home as clean as possible, use soy wax. Pouring your own scented candles is soothingly simple.
