First selection is colour. What will connect with the furnishings or what will contrast to add something to the room?
Second is size.How big is the wall it is going on? What pieces of furnishings are located below or near it? Are there any other distractions close by? Does the room have high or low ceilings?
Single art or groupings.Ideally, when doing property staging to sell, single pieces work best as you want a simple non-cluttered feel to the property. Bear in mind if hanging more than one, this will require extra hanging hooks and measuring, which all takes extra time. Sometimes due to the property style and furnishings, a grouping or extra art will be necessary.
If you do not have any suitable pieces of art then purchase cheap frames from your general homewares shops.”
