Many brass lamps of this style cost a lot. If you have found one model at a good price, take it, because they are expensive. Ask an appraiser about help in buying authentic pieces.
You can place them in the corner of the room, or if you have a few of them, then put on a cabinet, side table or shelves. Use the spotlighting to highlight these accessories.
If you have the very expensive lamp, then put it under the glass in a cabinet or on the mantle to make the original and rich décor.
Authentic tapestries in Moroccan décor style fit perfectly this style. Place the tapestries on the main wall, cover the center table or create the Moroccan seating with it. Some pieces of tapestries you may use as rugs but care about them because they are not meant to be stopped on.
