It isn't a blankie, per se. It's books. I have found that being surrounded by books has a significant positive effect on my mental and emotional well-being.
I have a bookcase full of books to my left at my new desk. I will have one to my right soon enough. Both in my peripheral vision while I'm at my desk working (which is actually a lot of the time, now).
At the old house, we had 400 sq. ft. smaller of an area to work with. We had three bedrooms, one living space, an eat-in kitchen, and a utility room/pantry. One wall on the living room had bookcases (not very tall), one wall had storage cubbies, and one had the TV and DVDs. Our bedroom held the majority of books that weren't in storage.
I love my children dearly. I love my children enough that I gave up having a library so that the pixie and imp didn't have to share a bedroom.
That actually put something like 3/4 of our books in storage.
Those are slowly being brought back out. The low bookcases that were in the living room now reside one each in the kids' rooms. Because their grandpa made them. We have a 3 shelf bookcase in the family room with kids' books in it, a knock together 5 shelf (modified with an extra from one that fell apart), a similar quality 4 shelf one (that will likely move to the master bedroom in a few months), and two solid wood hand made 6 shelf bookcases. Every one is packed with books, and most of our books are still in boxes in the garage.
By the time this room is finished, we will have three bookcases full of books on the long wall with the doorway, and maybe five on the opposite wall. The short wall shared with the family room has four big pass through openings from waist high to about a foot from the ceiling, and the outside wall has a huge window overlooking the front yard, road, and trees across the road. And this is where my desk is set.
For the past three and a half years, I've taught my classes in the university library. Even though I'm not surrounded by books in the classroom, the smell pervades. It grants a level of peace and serenity that I otherwise wouldn't have had. For the past seven years, I've been without the majority of books at home, because until we found and purchased this beautiful place, we simply didn't have the room.
Well, that, and we didn't trust the kids (particularly the pixie) to not climb the bookcases.
But now, the kids are older (and taller, and know where the step-stools are), and we do have the room. It may take a while (and a LOT of work), but my library is being rebuilt with solid wood replacing particle board.*
*The bookcases we had made of particle board were sagging, breaking pegs, and listing under the weight of the load of books on their shelves. I'm glad to have solid wood ones going in.
