Anything that is different, creative and quirky always fascinates me. The world of Art Dolls is a quirky one indeed. I would say these examples are in the premier league of creative excellence. All of these have been found on Pinterest and are by various artists. If I had the money to buy one I would. They are not 'dolls' they are works of art - please enjoy :)
Washi tape is a marvel, a wonderful invention, but it can be quite expensive. So if you are feeling creative and have time on your hands, here is a comprehensive, easy to follow guide, to making your own :)
Just one thing to mention, you are using double sided tape, so unlike normal washi tape, once its stuck it stays put!! This method is best used immediately after making.
