I have did an experiment that really came out pretty amazing and at the same time have been very educational. I have taken my old Chalky pastels and convert them into watercolors. Its a wonderful experience just by going through the process which I explain in detail in a PDF you can find in my Web Site… https://waltpierl.wixsite.com/waltartgallery
Once you have enter to my Web Site just go directly to Contact Me and the PDF will be right on the left of the screen. Just click it and it will open and you will be able to download it, read it just there, and actually printed. No Cost at all, just want to share my experience with this…. Hope you like this and try it..
