My mother-in-law gave me a pair of sandals. I thought the print was horrible: there was no way I would wear them! (you can see them on the picture) But my father-in-law told me I could paint them! (what a simple idea... I should have been able to think about it by myself ¬¬) And here's the result!
I used acrylic paint and varnish. At the end I added some studs and safety pins.
PS. If my mother-in-law sees them she will regret having given them to me :p
