A suggestion for the blog editors: please add a bit more content to posts like this (or make it much clearer in the photographs) so I don’t have to click through to find out what electro-etching is, and why I might want to do it.
A suggestion for the blog editors: add just a little more content to posts like this so I don’t have to click through to Instructables just to find out what electro-etching is. A new way to sharpen a knife? A decoration technique? A way to remove rust? Just one more sentence saying “Electro-etching is a process that creates texture differences on metal surfaces for decoration,” would be perfect.
Alternately, choosing clearer pictures (showing the results) would work just fine, too.
