This was a wooden perfume box. When I did this some years ago, I was going through a sunflower stage at home. I think I was painting our mailbox at home for my Mom. I channelled my inner Van Gogh here.
I used Acrylic paint and various gel ink pens to add some glitter and highlight some pieces. When it was dry, I sprayed the entire thing with Windsor and Newton's Matt Varnish, so that the ink pens would not rub off.
It held up well. This project is over 6 years old. There is only one bit of wear and tear, which was due to my extreme carelessness and before I added the varnish. I never fixed it but with varnish, it is extremely durable and long lasting.
