To make pure Cu(CH3COO)2 you need copper metal vinegar and acetic acid, you could also mix copper carbonate and vinegar. A third alternative would be
to pass an electric current threw an aqueous solution of calcium acetate with 2 copper electrodes.
Here's a link to youtube on how to make it: http://www.youtube.com/watch?v=mOpxpoOemN0

Just a note that vinegar is not suitable for chemistry use
I have a beaker of copper acetate solution that smells like burnt fish and chips with lots of weird fine precipitate. There's probably lots of
proteins left from the vinegar fermentation process.
As for the video putting beakers on those stove burner hotplates makes me sad

White vinegar's probably fine- malt vinegar is right out.

Hi, guys!
I've mixed the vinegar with the hydrogen peroxide, but instead of turning into a blue solution, it gets kinda orange-red. Do you have any idea why
this happens?

Oh, I forgot to say, that the liquid got pretty thick too.

hydrogen peroxide + food grade vinegar = a lot of nasty crap
food grade vinegar needs to be purified before use.
distillation will get rid of most proteins and sugars but not
some other stuff.
purification through freezing is documented in a number of
threads but may not get rid of sugars and some other stuff.
Also instead of mixing the vinegar and peroxide
you may want to drip the peroxide into your bath
with copper and vinegar.

Oh, I see! Thanks for the tip, man!
Also, I've found that brazilian coins are made of bronze! Does that have anything to do with the final color of the liquid?

Vinegar is very suitable for chemistry if "white" or "distilled" is used. The flavoured crap is not very good, of course, depending on the use.
Because it's availability I'm using it for most purposes and products can be usually quite easily purified by fractional crystallization, saturation
or evaporation.
For high purity acetic acid vinegar though, distillation is preferred.
