I have a small drawing table by my phone and if I am sitting in the chair by the table I just start drawing.
Here is one of my newest creations. I tried a new paper I bought from Amazon. Made to do wax and water coloring on it. It still curled a little but laid a heavy piece on it to flatten out after it dried.
The boarder is not even so it looks a little crooked but that is the way it is made.
