Step 15: Errors can be corrected
Just paint over the scratches, and you have a fresh canvas to practise your art.
Now I decided that the board can be made more compact if the programming socket is relocated, so it was done.
One final necessary step is to place dots of paint so that all pads are connected together - this is necessary for electrolysis.
In my board, the pads are all connected along the left and bottom edges. The scratches in the paint stop short of the edge. They will be cut apart after the etching is completed.
Now the board is ready to be etched.
