Oooooops, completely forgot to do this chart - and because I'm sorting out a load of stock at home I thought I'd just get it done and uploaded for you, so without further ado....
Remember for best results, print the chart onto the cardstock that you normally use for promarkers. I highly recommend Diamond White Super Smooth from Papeterie Crafts.
