There's no mystery to lavender's popularity: It can be used in every room of the house--to discourage insects, perfume the water in a bath, or impart its subtle flavor in certain dishes. Tucking scented sachets into closets, corners, and drawers is a lovely and centuries-old way to release lavender's scent.

Fold a piece of 8 1/2-by-11-inch paper in half the short way, and draw one half of a heart shape so the center is on the fold and the heart's edges extend almost to the paper's edges. Cut along the lines, and unfold the template. Fold the fabric in half, right sides together, and pin the two layers together. Lay the template over the fabric, trace the heart with tailor's chalk, and cut out the pattern.
Make sure the layers are pinned together, and sew around the perimeter of the heart, allowing a 1/4-inch seam. Leave a 2 1/2-inch opening for the lavender. Turn the sachet inside out, and press with a steam iron. Fill the sachet with the lavender florets, and slipstitch the opening.
To add a ribbon loop so the sachet can be suspended from a hanger or hook, cut a piece of ribbon to a length of 16 inches. Fold it in half lengthwise, and tie a knot about 3 inches from the top to create a loop. Hand-sew the knot to the top of the heart, and trim the ends.

Lavender is readily available in stores that sell dried herbs. If you grow lavender at home, harvest it when the florets have bloomed but not yet faded. Cut the lavender where the leaves meet the stalk, use a rubber band to hold a bunch together, and hang it upside down. Keep the bunches in a dry, well-ventilated area out of direct sunlight, which can evaporate the essential oils and fade the color. You can prevent the bunches from gathering dust by covering them with paper bags with holes punched in them. After the lavender has dried, strip the florets and store them in jars in a cool, dry place.
