Make soap last with a simple trick. Before you toss that sliver of soap, add it to another bar. When wet, the two bars will stick together. Let them adhere overnight and you’ll wake up to a uniquely layered bar of soap.
If you’re really creative, you can use this to mix and match your favorite scented soaps.
And here’s the opposite of this hack: if you want to infuse your bathroom with a nice scent, use a cheese cutter to take a few tiny slices (so small they curl up) of scented soap, and put them in a bowl or mason jar.
