Well I tried again this morning with this oil but didn't get far before I had to down tools once more. Tried wearing a mask and thought I had cracked it but although it wasn't as dramatic as yesterday when I started having pains in my neck, the tingling sensation started in my lips after about half an hour working. I'll put this one aside for a couple of days and have another try. Not actually sure that painting on Cad. Red Medium was a good choice either as it is very dominant. I was painting over the error of my ways with another painting I guess I should take note from the image below. I found it recently on Facebook and shall try to remember it every time something goes pear shaped...smile!
