Beautiful art!
Another way to preserve bouquets is to dry the flowers and add a few drops of an essential oil. Then keep them in a sealed container (glass rather than plastic) for a week or so. Then put small amounts of this potpourri in bowls anywhere in the house to enjoy the fragrance!
And still another way, but a lot more work, is to make beads from the petals. Very fragrant jewelry!
Thank you very much @donna-metcalfe ! Great tips! You need to show people how to do this.
I actually wrote a booklet on making potpourri, back when I had an herb shop! I sold all the ingredients and gave classes, it was a popular subject. (If you are really interested I can give you a link to its Kindle version on Amazon.) But I'm not here to promote that, and the basic information I suggested works well enough. Just petals and a bit of essential oil, keep sealed up for a while then enjoy. When the fragrance fades just add more scent, seal it up again, and repeat!
