Geoff, you have duplicated your posts here. Suggest you close one down or it can get very confusing. Sorry I don't know the first thing about wallpaper.

Thanks for posting new views of your room. You are right, nothing can go in front of the paneling, and we won't block the built-in cubby. In that case let's work with the rest of the space. I found a picture on Houzz for your gallery wall. I think this will allow you to bring in color and texture and interest to your wall without taking up space like furniture would. Try to play with portraits and a couple of paintings in there too - mix it up. Otherwise I would not put anything at the top of that landing (I'd remove that console table). That picture wall should be enough visual interest to your space and it'll draw the eye to the furthest wall as you walk in your house. I would try a small piece with closed storage between the bottom steps and that door by the entry. It looks like the space is no wider than 26", so it'll be a challenge to find something that fits and is tall enough. I would not use the wooden piece you showed above because you want wider proportions and fairly narrow depth so you don't bump into it as you walk by. (something like this ) I would hang a mirror on top of primping. By the cubby you could add a single seat stool. I'm not particularly suggesting these colors for the stool and bombe chest but something along these shapes. At this point if you do that big picture wall and add these two pieces of furniture and a mirror, you might not need to hang anything on the wall above the cubby. Also, I noticed your chandelier is quite substantial for the space and hanging pretty low. Would raising it a little or replacing it by something a little smaller be an option?

I can't seem to figure out how to get a great picture of a tongue and groove living room that also has ceiling molding, off of one of my houzz ideabooks to show you that this style you like, can and does look good together. I picked the collaborate feature and put your user name in it to try and share this pic.

I love all your ideas....bu as we currently have a new + good bin in there already, i don't want to spend another $100+ on another..and this is only a temporary solution...for the nxt few years..as the kitchen won't last much longer. I already have my 'kitchen' cleaning products under my sink..which is unfortunately a separate cupboard to my bin. We couldn't fit the bin under the sink! Prob not much point me taking the cleaning stuff out of my laundry to put in the bin cupboard!! I think i might put some plywood up beside the bin to keep one side of the cupboard separate! That way i have at least 1/2 cupboard of useful space!!
