You may wonder "What is a portière?". Portiere wall-hangings are defined by Wikipedia as: "A portière is a hanging curtain placed over a door or over the doorless entrance to a room." We need to expand on this regarding their use in centuries past and today. Walking through a French chateau or elegant Paris mansion you would see portières hanging on either side of doorways, adding to their grandeur. Several of these portières are available today, all being tall slim French tapestries. Since the visual characteristic of these is that they are both tall and slim they can be woven tapestries in other styles, not necessarily suitable for an elegant chateau. They may be suitable for a humble home (yours?).
Today portiere wall-hangings are much more adaptable for our homes simply because of the variety of styles. Yes, there are elegant designs but consider these too: medieval tapestries, verdures (ie forested scenes), numerous botanical hangings, even Art Nouveau portières. Several are available as pairs of hanging tapestries; visually a pair is far more than doubly effective than a single tapestry. These pairs might flank a door in the traditional manner but are excellent ways to decorate a large wall (see top image). My own favourites are the William Morris portieres in their Arts & Crafts splendour. Furthermore, they are unusually varied in sizes and colour tones. Seen on the right above, this one is the medium of three sizes. It is the green and yellow version; you can also order a maroon and brown alternative, also in three sizes.
