For all work that is to be exhibited you need to ensure that it is ready to be hung.
Please ensure that there are D-rings, or other suitable fixings on the frame or back of your art.
Make sure that suitable cord is attached to the D-rings or frame securely.
We would prefer the use of cord rather than wire if possible as there have been instances of wire cutting our hanging team, but if you do use wire please make sure that all ends are safe with no frayed bits of wire sticking out.
If you are exhibiting a canvas, providing it is ready to hang, as per the above, if does not have to be in a frame.
