These were all done since I've been back. I used Coptic pens and Micron pens. The paper is Fabriano Drawing Paper, 224 gsm (I cut my cards from the larger sheets, A3 or A4 usually). The last card Kate B. cut for me from some of the Penguin Clubs drawing paper (I ran out of the cards I had brought and she was really sweet and cut some new ones for me). It is quits a bit thinner and whiter. The pens take to it differently due to its composition and lack of texture.
Have a great day!
