Borax is an inexpensive naturally-occurring mineral with many household uses. You can even dry flowers with borax for household floral arrangements.
Time Required: 1 week
Cut flowers you wish to preserve, with or without stem.
Sprinkle borax on the bottom of a small box such as a shoe box.
Add up to two flowers.
Completely cover with more borax.
Tape the box shut.
Let sit at room temperature for about one week.
When dried completely, strain off the borax powder; may be reused for more flower drying.
