What about empty perfume bottles. Do you to know if you can recycle them, how to reuse them or what? What shape and size of bottles? Are they glass?
Depending on what the bottles look like, they could be used as decorative accents on a vanity tray. You could also use them to hold small flower arrangements. I think mixing a bunch of glass bottles together is a great way to create a timeless, vintage look!
Fill the empty bottles with water. Leave the caps off. Put one in each toilet room and bathroom. Put one in each bedroom. In a child’s room, you may have to place it up high or clamp to a door sill. The scent will last a long time, but when it wears off, put in your favorite essential oil. Don’t neglect the kitchen! Best wishes, ☺️
I’d use them as mini flower vases. I saved the mini glass bottles that IV drugs come in. They are so cute with violets, grape hyacinths, lily of the valley, etc. I have flower gardens so always have access to 'free' flowers.
