I did a comparison of two flowering plants that are forming mattes in my currently fallow garden area. It really did help to focus attention on various details doing the comparison. The two form very dense mattes, and appears there is some type of competition going on between them. Putting two items on the same page is a great technique!
What inspired you to begin nature journaling? I worked in natural resources for almost 35 yrs and I am drawn to natural settings. When I retired I took a drawing class with the thought of eventually learning to paint, which I have always had an interest in, but never really done. I now have taken a watercolor class and most recently did a class on "30 portraits in 30 days" to get over some of the "fear" of drawing people. Then this class popped up and seemed like a good next step. I love the mix of art and thoughts / observations and how each can stimulate the other and this seemed like a good way to explore that. I have yet to develop a daily habit of art, and classes seem to be a good way to encourage me to work on art. Most of my work is from photographs - usually what I have taken, so some work in "plain aire" mode would be good. Writing notes has always been a good practice for me to better remember things, and I am intrigued by the role that art might also play in that process.
