Here is a step-by-step process to dry flowers:
Step 1: Figure out what flowers you’re going to dry.
Step 2: Place the flowers in the oven on a cookie sheet and turn it on to 240°F or 115°C.
Step 3: Leave them in there for about 3 hours before removing them and waiting until they are cool enough to handle.
Step 4: Place each flower on a paper towel and pat it dry with another paper towel. Gently rock the flower back and forth to remove water from both sides of the flower.
Step 5: Put drying flowers in an airtight container, preferably one that’s dark, for 24 hours before putting them away somewhere safe.
Step 6: The flowers should remain pliable and flexible. If they are too dry, re-hydrate them by placing a wet towel over the container and letting it sit overnight.
So this is how to dry flowers.
