Dry Hydrangeas in a Microwave
You can dry any flowers that don’t contain a lot of water in the microwave.
I prefer drying the flowers in a microwave because the flowers look more natural than when you press them flat and less curled up than when you let them dry naturally. But I always dry a few florets naturally and a few flat from each mop head just to have some available when I need it in a design
As a guide:
The florets dried from a strawberry milkshake pink to a Victorian purple, green florets dried to a pale green grey and rusty red florets dried to a pale burgundy and green
Press the florets between the pages of a heavy book to dry
