I came across two amazing and simple DIY accessory projects on a German blog called My Stolt. I think all DIY projects should be this easy and cool. All you need is some small neat shaped plastic children's toys, gold spray (or any other cool color) paint, glue and some ready-to-go jewelry supplies. The links below the images take you for the full tutorials. Thank you Meike for these!
Ps. I'm in love with the pyramids ring!
