First Time Etching

I've been wanting to try a new technique for some time now. The idea is to use an acid that will etch copper, but leave places to be protected from the acid and then when finished you will have the imprint on your metal.

Of cause I messed it up, but I wanted to show you my results anyways...

First mistake - used way too thin sheet metal (26ga)

Got my circle cut out now...

Cleaned the metal from any grease or other stuff...

Drew my little fairy picture...

Final product got way too etched cause I forgot to put resistance on the back...

Now oxidised...

Couldn't bare not to use it, so made this little piece out of it. Wont put it up for sale though, this is just for me.
