HINGED

Map ed Veveiis, artist's book by Genevieve Seille  

"Hinges, by definition, are not autonomous -- they can exist by themselves, but for them to perform their function, fulfill their humble nature -- they rely upon other completely different, yet intertwined parts"  -  M. Snowe

Shrine by Donna Flax  (I believe Donna runs workshops but I havn't been able to find a link).See more Altars, Shrines and Holy Thing on Pinterest, here 

Artists use hinges in any variety of ways 
Some hinges are used on doors 
Others to join two or more elements together
Found hinges are adapted to create jewellery or mini sculptures....
and then there is the hinge that  serves no purpose at all except to look rusty.

Artists are known to be resourceful and will create their own hinges
Some are as simple as a few loops or  ties connecting several pieces together
Others are more complicated.
