One recent acquaintance is this rhinestone necklace, which I got for only 3euros (three!) at H&M.
The initial excitement was poised by a slight sense of disappointment; by the time I brought the "goody" home, had I realized it was way too flashy for my current state of style and mind.
Instead of regreting, I got my nail polishes on the workshop table, quite a lot of patience and after a couple of hours...here I am: a proud owner of a transformed rhinestone necklace, that now perfectly matches both my style and my coral pink toes!
Hope you enjoy the idea as much as I did. Why don't you give it a try on an old jewelry piece?
