Im not sure where I would want to go to buy wire?.....I can imagine where you'd obtain wire from (maplins, hardware stores, b&q etc) but Im after a wide selection of thicknesses and styles.

Im producing wire sculptures for my a level art....and will not only need thick wire for the main structures, but also very small-holed chicken wire and almost soldering wire thickness wire for more detailed areas.....
Also is there a variety of wire that's almost very thick foil with hole punch sizes holes all over it? (I need that effect.....so if it's not possible I'll just have to produce the holes in it myself)

Any ideas...?
I fancy one trip, to a self service store of some description....so really I want some sort of wire warehouse =)
