Glycerin soap is both quick and easy to make. Many craft stores sell bricks of premade soap, dyes, and fragrances. To make, follow the directions on the package to melt the soap, usually in the microwave, then pour it into a mold. Drip in enough dye to get the color you want and add your favorite fragrance.

Warm apples are a quintessential fall smell. Unfortunately it's very difficult to replicate that smell using real apples. The natural scents in many apple fragrances are derived from distilling essential oil from the fruit's skin, and it's difficult to make.

Bypass the headache; purchase apple essential oil and grab the cinnamon from your spice rack. As pictured, clear glycerin soap also nicely displays glitter and slivers of dried apple. Shaped soap molds or cookie pans let you make fun, seasonal shapes.
