Dried flowers are super easy to look after. They may be fragile, but they will last for a long time if looked after well.
1. No water please!
Keep them warm and dry so they will last
2. Avoid direct sunlight
This is to prevent them fading over time
3. Good airflow
Prevent temperature changes and ensure good airflow They do not need airflow directly from an open window, but in a damp room they may become moist. Some vases may also capture moisture, so check now and then to make sure they are nice and dry
4. Dust with a feather duster
(If they need dusting!)
5. Be gentle
Best to avoid knocks and keep out of reach of small children or furry friends
