Here are a few potpourri pointers:
Scatter potpourri at the bottom of silk- or dried-flower arrangements, in any decorative vase.
Pin sachets to the backs of draperies, where sunlight will draw out their scents.
Slide sachets between the books on bookshelves.
Tuck sachets underneath sofa and chair pillows.
Tie a couple sachets to chair backs, bedposts and headboards.
Slip sachets between guest linens in your linen closet.
Scent your stationery by putting a sachet in your writing paper box or desk drawer.
Toss a sachet in the clothes dryer next time you do laundry.
