The term installation is sometimes applied to permanent, site-specific, sculptural ensembles created for corporate or public settings. But it also applies to short term displays that are larger and more unusual than the worship display created for a prayer focus in a Sunday or weekday service as installations take a little longer to 'install'.
Inspiration for beautiful worship centres by Stella Bristow
You may wish to create a worship display occasionally instead of a flower arrangement, using materials relating to the theme of the service. Creating displays requires a squirrel mentality – an eye for seeing potential in a piece of wood or a stone and in other people’s rubbish as well as your own! As you gather items together, you may need to dedicate some storage space to your collection.
