Glysophila, also known as baby's breath, is a flower commonly used as filler in flower arrangements. It does well as a cut flower, and dries easily. When dried, the glysophila does not look very different than a living version. Baby's breath is susceptible to fungal infections while in vases, so inspect the flowers for damage before you try to dry them.
Select a warm, dry area for drying the flowers. The spot should have good ventilation, as gypsophila releases ethylene gas while drying. There should be no other flowers nearby.
Wait for the flowers to be near the end of their vase life before drying them. This allows you to get the most enjoyment out of the fresh flowers.
Gather the gypsophila in a bunch and secure the stems by tying a rubber band around them. Tie the loose end of a string around the rubber band.
Tie the other loose end of the string around a hook, nail, rod, or other hanging surface in the drying spot. Leave the flowers to dry until they are brittle to the touch. Remove the rubber band.
