It’s hard to be a “neat” painter. This is the easel I used for most of the paintings I work on at home. It’s messy but I need my stuff close at hand in able to work effectively.
And it takes a lot of “stuff” not only for painting, but also for framing, matting, hanging, promoting, marketing, etc. An artist’s studio or work area often is filled with materials and “stuff”!
The Studio 
I love seeing artists’ work spaces.
I saw a t-shirt once that said”creative minds are seldom tidy.” I must be really creative. You should see my house!!!Yikes!
There probably would be no creative process going on if you had to worry about straightening while you worked.
I hope Jed is better.
