These are the last two pages of study from the book I've been following. Some of the lines on the above piece were done with the edge of a mat board and some with thinner board. I've used acrylic ink, homemade ink and a stamp pad for the different colors.
The lettering page was designed to show different texture created from size, style and layout of letters. OK, this was pretty easy for me as I was a professional calligrapher for 29 years. Still, since I've barely done any lettering since I retired, it was fun to do.
