1. 'Little white dog'- one of the heated kids crayon batch from yesterday, which I found the dog image in today.
2. 'Bookmark'- water soluble wax and oily wax crayons.
I tried out some water-soluble caran d'ache crayons this morning on a scrap of orange pastel paper. I wanted to see the effect of using the soluble crayons under the wax crayons. The soluble crayons gave a good undercoat of solid colour when washed over with water on a brush- rather like magic painting books for kids. This will save me a lot of effort in oil pastel work where it can be difficult to get rid of little 'holes' of colour in the paper...even when using a blender crayon or a blender tool. In future, I will use the soluble colour under the OP to get a good covering and hope to get around to trying this technique out in a larger size of work tomorrow. I have always avoided water-soluble crayons in the past. I can see I might get addicted to them!
