I am challenging myself to fill a 100 page sketchbook with all doodles using BIC ultra thin permanent markers. I love them! I got a pack of 36 (I think) at Staples for about $20. I have done about 70 pages and several of the markers have finally run out. I replaced a few last week including the black (which I have replaced several times). Obviously I use that one a lot!
I also found a Sketchbook Challenge blog HERE. They have monthly themes for you to follow. April's theme is open: as in flowers, doors, hands, whatever else you can open...your eyes. So here are the pages that fit in the topic.
I am thinking about making some of them into greeting cards. Any suggestions as to a site to use for that?
