Copper in solution can be super saturated and dip deposited. That is normally
a thin layer at best. Plating is the best way - take a copper
pipe/sheet/wire.... and the sheet you want as the other electrode.
There are reasonable web sites that show electro-plating and offer chemicals
to aid and do the whole job.
Often large crow feet are used with the object suspended above the foot.
