One of the bloggers who I have followed for a long time is Maggie Latham.

In addition to posting her own wonderful work she often teaches on her blog. She is presently doing lessons incorporating permanent ink with other water media. She started the lessons just as I was on the road to my workshop in Myrtle Beach so I am trying to do a few of them and catch up. I don't know if I will get to all the exercises but it is fun to see what she recommends doing.
I went to the Suffolk County Farm and Environmental Center in Yaphank. My favorite all time view there is from the exit ramp on the Long Island Expressway. You can see many of the small barns across the field as well as the silos. I have painted this a few times before. For safety reasons I always do this view from my car (NY drivers are crazy.) and every time I sit there I expect a police trouper's car to come over and see why I am sitting there for so long, but I guess they are too busy chasing down speeding cars. lol
Here are the three quick sketches I did.
I did the top sketch with my dip pen, a small brush, a bottle of India ink, and my water brush. I did have visions of spilling the ink in the car, so I made sure to put a towel on my lap for protection. Then being a colorist I couldn't resist adding some alizarin and yellow ochre tones.
The second sketch was done just with the dip pen and brush and some water from the water brush.
The bottom one was done with my Lamy pen with brown ink that is not very permanent.
Thanks, Maggie for some good ideas. I'll have to try a few more of the ideas you showed. I know my Myrtle Beach sunrises and palm trees are calling out to be combined into something.
