I just love this technique. Before I added a wide range of colours to my inks, I used this often to add colour.
Here is a card from my gallery. I made this special occasion card for my in-law's anniversary. They just loved it.
(the script was chalked, then once it was dry, I Versamarked the flower over top).
(All of the flowers were versamarked and then chalked. It was very time consuming! The smudges are where all of the family signed it.)
