Alphabet – next step

Once cleaned, here are the letters from my alphabet (technological miracle, I inverted the pic so you can see them on the right side).
As you can see, I made a mistake on some of them, the ones that looks inverted after being inverted :-/

Moreover, my printing tries are just awful, so awful that I won’t show even a bit of them.
I tihnk I’ll have to restart from the beginning, differently, with more care, briefly : to be followed…

To make you wait, here is a pic of the residues of the cleaning which is, probably, the best thing I got out of it.
