Gayle...what an amazing and I am sure a very deserving room!! I love the outside light capability too!! Here's what I'd think about for you and a design wall...if you can reach..(stand facing at the wall) open the top left...then 4 doors over...that would prob be a good size for one. All you'd have to do is glue a strip of velcrow inside top of both doors (so when closed you won't see it-and you can remove when done to close too)then sew velcrow on a piece of white flannel...open your doors..put design wall in place...there you'd have it! Just a thought:))Then again...we are seeing patio doors...to where???Maybe it's time to hand dh that hammer and tell him it looks so good...we vote for you to have more!!!:))Keep building:)) Also remind him you surely have doubled the realestate price in that house:) Makes sense to just add more:)) Enjoy!!
