One of my blog visitors wondered if using wax paper over white cardstock in an embossing folder would transfer enough wax to the cardstock to be used as a wax resist. I gave it a try because all the tools were sitting right at hand. Unfortunately, not so! You can see to the left my experiment. The second from the left is the cardstock I put through the embossing folder and painted with watercolour. It has a nice relief but it did not resist the colour. I decided to transfer the wax to cardstock using heat. I placed my embossed wax paper over a piece of white cardstock and wrapped it in white paper and applied heat with my iron. The cardstock has a VERY faint image of the design once colour is added - it is the far left. The cover paper I used had a much better image and resisted the colour very nicely - it is second from the right. On the right is the wax paper!! It looks interesting enough to be used as a layer on a card!!
My visitor does not have an embossing machine so I tried using just crumpled wax paper and created the paper on the left - wrinkled wax paper (left) and the resist paper on the right. You can create all sorts of patterns in wax paper - fold, draw, etc - that can be used for wax resist.Thanks for asking!!
The two following scans are of the tissue I used as a paintbrush for the application of colour in the above experiment and the two sheets of copy paper I used to dry them with the iron. I did not expect the colour to transfer. 
So one little experiment!! 10 pieces of paper I can use in my paper crafting!!Everyday is a good day to play!! I may use these later today when I am working on challenge cards!!
