I modified the challenge a wee bit. I didn't use the same paper for the various drawings since I was using (top row, left to right) hard graphite pencils (3H to HB), watercolor pencils, (bottom row, left to right) brush pens and ballpoint pen. These media work best on very different paper textures and moisture absorbing qualities. The second picture shows the object of my study --- and the apparatus I use to hold botanical subjects. "Third hand" tools are very useful and cheap. This one was under $10 and serves my purposes well. Just FYI. (Each drawing/painting was scanned and composited in Photoshop.)
I do generally put pen (or some kind of tool), to paper (or some kind of surface), every day, but I'm really TRYING to do it purposefully in one singular location (journal). Here is a successful attempt from that particular day.
I'm also super lazy, which means I never go up to my actual studio and only use what's out on my computer desk.
A fun drawing to do. I usually do a lot of crosshatching, but for this one I went for the smoothness, better to capture the light, I suppose, where crosshatching can be a little distracting. Or look like hair! As some have said.
BIC ballpoint stick pen drawing on Richeson bulk drawing paper. This started as a contour drawing and just got squiggly (not the original intent). This was clipped to my board for weeks and I would add a few squiggles from time to time when I wanted to make marks, but didn't have inspiration. It's just a bit under 15 inches (12x18 inch paper) and is probably about 25 hours of making little lines and squiggles. The reference was a Dreamstime royalty-free photo.
