You can really see the contrast when you compare these two pieces of carpeting side by side.
Carpet two direction.
They are just laid with the nap facing opposite directions.
Carpet pile should run in the same direction throughout the house sweeping towards the main entrance.
To keep your carpet looking like new it should be cleaned with a carpet cleaner at least once a year.
Ideally you would install carpet on stairs as if the roll were rolling down the stairs.
Although your carpet cleaner looks very much like a regular hoover vacuum it uses water and a carpet cleaning solution to remove dirt and buildup from your carpet.
On stairways the pile should sweep down.
Think of it like this.
Carpet tiles will have arrows on the back that indicate the direction of the carpet pile.
I bet no one will notice the pattern change.
It looks like your carpet pattern would not make a difference in layout.
Then bring the entry hall stair carpet up to the landing.
Any two carpet tiles facing in different directions will appear to be slightly different colors.
Carpet does have a direction usually indicated on the carpet backing.
Carpet comes on a roll that s 12 feet wide and runs well essentially to infinity.
Generally seams should run in the same direction as most foot traffic.
Run the carpet up from the kitchen all the way to the second floor because it is a straight line of sight.
Orienting the tiles in the same direction will create a seamless look.
This is what i would do.
See these three different colors of carpet.
Actually they are all the same color of carpet.
