This was my final decision. Judy Paul's "Garden" ordered off of Overstock.com. It is 40 in. x 40 in. so I hope it will be big enough for the gaping hole above my couch. I love the weirdness of it, and I think it will bring some much needed "life" to the room. Later on I might order a second piece from Judy Paul that is similar. She has 6-7 that are this style but with different pictures and sketches and designs. But for now, this will be it!
Thank you for your wonderful patience and advice! I can't wait for it to come in so I can finally move forward on the rest!
