This is a rear view of a multiple hanging. You could hang three or four pictures in a vertical line in this manner. You could also combine an inverted V arrangement with a Double Vertical Drop arrangement (see Image C). This illustration uses chain, but it could also be done with cord (see Image D).
This is a Double Vertical Drop arrangement using chain. The inserts demonstrate how the O rings and S hook are used.
This example illustrates the use of two rosette picture hangers using cord on one hanging. This works nicely, if you have a very wide hanging. It's best to give me call if you wish to use this method so we can figure out together how much cord you will require.
