Thank you Arty
.... knife, brush, nail punch, fingers, credit card. Whatever was close. I went with color into and over color ... no rules; just freedom of expression with an accent on light and life. If it wasn't working, scrape it out and have another go at the particular passage that was nagging me.
I had a nice little square knife that I did not like when I first got it because it's marks were so different most times but then I fell it love with it because of the variety and unexpected marks. However, it was cheap and finally broke under the pressure I put on it. I just may have to find a better version of it. Cheap knives are not tempered properly so the flex is missing.
