Uh, Chris, you aren't electoplating the spoons, you're just depositing copper granules on the surface - which is what we did in Chemistry class, too. True electroplating requires either a strong alkali (usually a cyanide solution) or a strong acid (usually a hydrofluoric acid solution) to react to the two materials and form a bond at the molecular level. Depostiing copper on the surface creates a thin, rough (granular) surface that will flake off easily. Sorry.
The copper sulfate technique is also a deposition method, although it gives the object a smoother surface than other techniques.
I hope it works well enough for your spoons, 'though. Please be careful with the copper sulfate solution, it's damned toxic.
