Another Small Studio- Need help with windows

Hello Everyone, I just closed on my first house and can't wait to get started setting up my studio in the guest room. It is a small room (approx 10' x 12', 8' ceilings and hardwood floors) and I plan to use it to record and mix/edit. I figure I will need a lot of bass absorption due to it's size as well as a bit of High/Mid absorption as well. I was planning on using OC 703/705 to start since my budget is tight, then later build boxes when my budget grows. My concernin this room is the placement of the windows- there are two that meet in one of the corners-each 39" long. I plan to build window plugs, but just don't know what to do for the corner absorbers. I have attached a drawing of the room, and eagerly await any advice. thanks in advance, Kini
