Why tall ones a t all why not lower ones and on both sides if she needs lots of book storage.

Thanks Patricia. I thought something tall would add visual interest to the big blank walls. In addition to books she has picture frames and other items to display.

I would put desk with a lamp on left, a drape on window to soften it, a basket or two in front of window and a bookshelf on right. (Make sure to bolt to wall). You could put a colorful print over desk to add some color and height.

I would center a tall one on the left (wider) side.

Then for sure go lower to use the wall space for other stuff she has. I would suggest some cork boards for diplay of pictures , ticket stubs etc. it will save your walls.

I would put the papasan on the right, desk on the left and a low bookcase under the window. Add art or a poster above the desk to get the visual up higher.

Whether tall or low, you could go wall-to-wall with the bookshelves. You could leave the desk where it is in front of the window but have the top shelf continue over the window if you choose a tall one.
