Household!
The tradition to fly household pennants in Finland is quite common. A pennant can be flown whenever there is no flag day and it is usually a means of telling that the “master of the house” is at home. These pennants - commonly called Isännänviiri in Finnish orHusbondsvimpel in Swedish - have a long, narrow, triangular shape, usually half the length of the flag pole. The triangle has a base of roughly 1/10th of the length and it is connected to the pole via a single lanyard, giving the pennant the ability to rotate while flying[1].
The different regions of Finland have been connected with some traditional colors (often from the regional coats of arms), and these are often reflected in the household pennant. The pennants sometimes also incorporate the regional arm into the design (as seen in thisexample).
