Drying flowers

I just read this on a website. I have not tried it -- has anyone here?

"Preserve flowers: Mix one part 20 Mule Team Borax and two parts corn meal. Fill the bottom one-inch of an empty airtight canister with the mixture. Place the flower on the mixture, then gently cover the flower with more mixture, being careful not to crush the flower or distort the petals. Flowers with a lot of overlapping petals, such as roses and carnations, are best treated by sprinkling mixture directly into the blossom before placing them into the box. Seal the canister and store at room temperature in a dry place for seven to ten days. When the flowers are dried, pour off the mixture and dust the flowers with a soft artist¹s brush. Borax removes the moisture from blossoms and leaves, preventing the wilting which would normally result."
