3. Dry them in the microwave.
If you haven’t got time to wait, using the microwave can help to dry out flowers quickly. The result will be the same as pressing the flowers. You’ll need two flat microwave-safe dishes and some paper towels.
Place a layer on top of one of your dishes. Then arrange your flowers in a single layer. When you’re happy with the arrangement, set the other dish down on top of them (we prefer using glass for the top dish so we can still see the flowers).
This can be put in the microwave for 20-30 second. If your flowers have a small size, you should allow them to dry out after the first cycle. For those that aren’t completely dried out yet, continue microwaving in bursts of 15 seconds, checking each time if they’re dry. They shouldn’t brown – if they do, it’s been too long.
Some people suggest submerging the flowers in a layer of cat litter or silica gel before putting them into the microwave, but we wouldn’t recommend that for health and safety reasons.
