Well it all depends on your view from your window....hmmm...I've got the 2" faux wood blinds, and dark chocolate thin drapes that are always tied back and blinds open. I find alot of inspiration from nature! And my sewing room/guest room is on the 2nd floor over looking my gardens & woods. I bought my curtains from Walmart for $9.99 and they look really 'high end', but they are thin; however they are there more for 'looks' than purpose.
Here's a great idea....if you've got a few too many quilts, how about using them- they would serve 2 purposes: design inspiration and wonderful decor AND they will keep the cold out and in summer keep the heat out!
I love the quilt blocks on your desgin wall, how about making a few more of them- they are really tres chic, and very warm and inviting....they would be fabulous as curtains!
