Wallpaper with repeat!

Hello!
First of all, the wallpaper is very durable on the material. Looks looks really fantastic and could be put by me, who has wallpapered the first time in his life, absolutely straightforward on the wall.
The product is brilliant!

I prefer, actually unjustly, a ZIP code, because:
As mentioned above, I have papered the first time itself.
The wallpaper with patterns and especially Rapport is a real challenge for newcomers.
Mathematically, would have been enough, because I wanted to risk anything, I have 4 ordered 3 rolls.
Thank God!!
Without the role 4. I would have been screwed.
I had blended almost a whole roll because I first had to google how to repeat now properly "used".
Ultimately, I did it by "judgment".

Why you can as wallpaper manufacturer not a guide for idiots (like me!) How to attach the glued wallpaper to fully blend have no NEN belly ?!
