I love the washables because I love to be in creative control. I love to have options, I like to have choice and I like to do what I want in what ever colour. So the idea of washables was born, they are the burger king of the paper world, you have it your way! Now because they are printed on the beautiful stamp and colour paper they ink brilliantly, so all the inky techniques in previous posts work on washables, but have the added bonus of that design shining through. A really easy and effective use of washables is a nice crayon resist technique. I used the bauble washable from the Christmas pack for this. I then took a white crayon and added highlights to the edges of the design. Then all over the top with with a distress ink, where the white crayon is you will see the design pop! Buffed it with a bit of tissue, just to remove any residue ink off the wax, and my own designer paper is finished. A candle can also be used for different effects.
Nothing I do is overly complicated it might be different but not difficult, so. give it a go.
