My windows are pretty much covered all the time because UV rays are harmful to paper. My studio is never too humid or too dry. We don't have pets anymore, but even when we did, pets were never allowed in the studio. It's a big no no for me. I have work tables and chairs, many shelves and storage, piles of books, art works, frames, a paper trimmer, a mat cutter, a handheld vacuum cleaner, a dry mop, and of course lots and lots of paper.
