Wallpaper research

I am collected samples of wallpaper from Farrow and Ball. I am getting the right measure that are used on general wallpaper so that I can get this all correct. I want my wallpaper to be viewed as thought it could really be used, even if it is being made for a shop interior, it could be used else where, for example a young teens bedroom would be perfect.
But it also needs to be right in the way that the pattern on the paper needs to be perfectly in line so that it can be matched up to connect to the next sheet of wallpaper.

Here are the ones that I have collected.

The following wallpaper sames are from Farrow & Ball:

These two I ordered samples of because I believe that they relate well to my designs in the way they are quite simple with a lot of white space.

I see a lot of wallpapers in shops and also in peoples houses which have a lot of white or plain space and so I think I want to use this for my design on the wall paper. I think that it will work well but even though I plan on using colour within my design I want to make sure that they space is used correctly and efficiently.

I am going to look into getting my wallpaper printed on to the correct type of paper. I think that will also give it that little more authenticity that it could well be used in a shop/interior.
