Drawing papers for wallpaper

I bought three papers for the interior, all drawing papers in large size sheets. The side walls are longer and taller than standard scrapbook paper sheets, so this will eliminate the need to piece the wallpaper. I have successfully applied wallpaper with seams before, but why bother if you don't have to? And, solid papers tend to show seams more readily. I will be using the back side as the right side surface since the texture is softer.

I bought Daler-Rowney Dreadnought Grey as well as Canson Pearl Grey and Ivory. The ivory is for the bathroom and the greys are for the main hall and living area. I loved the Dreadnought Grey in the store but worried it might be too dark for the interior, so I bought the Pearl Grey just in case. I might use a two-tone treatment.

I think it's rather fitting to use drawing papers for an artist's studio, don't you?
