What can I spray on dried flowers to preserve and keep them stiff?

Hello! There is an acrylic spray that is sold at craft stores, specifically for coating dried flowers and preserving them. Good luck!

You use a silicon gel to preserve flowers, or air dry them in a dark place like the garage hanging upside down using string to tie off the stems and hang from the rafters or in the attic. I used to do the air drying method when I made lots of dried arrangements for the table or wall. https://www.wikihow.com/Preserve-Flowers

I also as a botanist in addition to being a wildlife biologist used to collect and press herbarium specimens for the provincial herbarium.

Never heard of a spray, but it might be new, check Michaels or Hobbylobby.

I have used a hairspray that is a high hold. Spray outside and let dry before arranging in a vase.

I did varnish. Worked great.

Hairspray

Hair spray works ...even better lightly spray with clear matte spray sealer.

Hair spray, but only from an aerosol can. It will come out too gloppy and weigh your flowers down in a pump spray. Also there are clear sealers at craft stores.

I have always heard people using hair spray.

Hi Ginger, hope this helps,

A gentle burst of clear spray paint is all you need to preserve your pressed flowers. They need to dry thoroughly after being coated with spray paint. I use bowls filled with sand to stand the stems/toothpicks in. You can also use sand-in-a-fancy-dish to make a pretty flower centerpiece! Rustoleum makes some nice clear coats

Using a can of ordinary hairspray, you simply work your way around the rose covering the petals, stem and leaves with the liquid. The hairspray holds the petals firm and prevents them from falling off while hung upside down.
