How to mix patterns

Now this is super cool

Bookcase: Wally / Random lookalike

I really like bookcases with shelves of different heights, like the Wally by Cattelan. It's cool and modern and fresh and less deep than 27 cm (I have an annoying niche thing going on in the lounge):

Or the Random by MDF:
 

Thing is, I don't have the right budget...

I have then thought about getting the Osaka by Maisons du Monde, a lot cheaper

And if I place three next to each other it would look something like this (yes I'd like to get a Fornasetti plate as well...):

which I think is quite cool and has texture and movement... And a fifth of the price as well :-)!!

Vertical and horizontal lines in my living room

I am trying to understand if I would like to put an Ikea Liatorp bookcase at the side of my sectional sofa.
And I am also trying to figure out an original layout for a wall unit in the 27cm deep (ehm... shallow) niche in front of the sofa.

I am trying to learn more about horizontal (the sofa) and vertical (the bookcase) lines and I have come across this website
Lines in design – Interior designers talk composition with lines

It's interesting and it also talks about pattern: apparently a big scale pattern is less busy and makes the room appear bigger.
A high mirror makes the room appear taller but it is good to keep the rest of the furniture quite low if this is the aim.
Horizontal lines (hear hear ;-)) make a room appear wider.

Some new favourites at Ikea: turquoise...

The Vettre nightstand thingy.

It is so cute, I'd like to put it in the living room or something.

The Frode stackable chair, it is turquoise AND (weirdly) comfy too.

The Snekkersten rug was very cool as well, it would look good with my taupe walls (though maybe too matchy matchy? Maybe not as it's a pattern I guess).

Ah and Snekkersten apparently is a place in Denmark, I had to look up a name like this ;-)

Living room: Ikea Nornas + Forhoja?

Will I went to Ikea today to see the Billy bookcase with doors, but I don't really like the look of it.

I think I'd prefer a material that didn't pretend to be something else... Natural wood looks so much better but my budget is not massive and I also need the bookcases to be shallow as they will have to be in a niche.

All the bookcases seeem so boring...

Then I saw the Nornas chest of drawers... it looks really cool and original and I guess it could even look good in a living room.

But what can I combine it with? I thought about the Nornas bookcase and maybe Forhoja wall shelves above.

I could maybe paint the Nornas chest in different colours (white, grey and possibly also some turquoise)?

Update the day after... 

It looks too busy and gimmicky, I think I will get some built-in shelves done when I have some cash, probably 25 to 26 cm deep as the niche is so shallow :-/...

Hot AND blue. Warm blues vs cool blues...

I have just read something about warm blues vs cool blues.
http://www.realsimple.com/home-organizing/decorating/decorating-blue-ideas/ad?slide=3

Warm blues contain hints of red and some of them are denim, ocean blue, or slate blue.
Warm blues come forward (instead of receding like cool blues) and they create a cozy atmosphere.

Apparently (according to Bunny Williams on Elle Decor) you can mix warm and cool blues.

Another website says that if you want to use more than one accent colour, you should use only bright or greyed ones and not mix the two.

I think I want to use a neutral palette of taupe walls and warm grey furniture with warm blues (and some cool ones) as accent colours.
