How do you pick size?
Livingroom: If you want a rug by the corner sofa or chaise longue, the rug should stick in 1/4 - 1/2 of the sofa's depth to anchor the sofa. Or just place the sofa(s) next to the rug.
Kitchen: The rug under the dining table should protrude about 60-80 cm measured from the table edge. Then all the chair legs on the rug will be accommodated as you pull out the chair to sit down at the table, and it is easy to slide the chairs in and out.
Bedroom: If you put it under the bed, the rug should stick out about 60 cm, so you can walk on the rug around the bed.
How do you pick colours and design?
With the rug as a starting point: When you decorate a room or an entire home, it is not uncommon to leave the choice of rug last. Instead, try to use the rug as a starting point and decorate the rest of the room with furniture based on your rug choice. It can be an exciting way to decorate and will perhaps help you find a new style.
