This picture frame is all made with cardboard and the mosaic is made with...eggshells!
I've always wished I could make mosaics but I never had the materials to do them so I thought that I could still do whatever I wanted recycling what I don't need anymore.
Just like with all mosaics, you need a lot of patience, but the result is great and the feeling of satisfaction you get looking at it is worth the time and patience, believe me!
First of all you have to make the frame.
Take a piece of cardboard and draw a rectangle: you must consider how big the picture you will frame is. Mine is 13x18 cm (5.11 x 7.1 inches) so, adding 4 cm (1.57 inches) on every side for the frame, my rectangle is 21x26 cm (8.28 x 10.23 inches).
Cut the rectangle and make another identical one so you will have 2, one for the front frame and one for the back.
Take the first rectangle and draw a 13x18 one in the center counting 4 cm from each side. Depending how big your picture will be, your measures will be bigger/smaller. Once you have traced this last rectangle, cut it out and you will finally have your frame!
