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.
Lovely for parcels, letters, envelopes etc..
