Hiddur Ayin and Dalet
Rav Ben Tzion Abba Shaul and Rav Mordekhai Eliyahu say that if the Ayin and Dalet do not at least touch and preferably cross the sirtut of the line below the resulting tefillin, mezzuza or S"T has no hiddur. I'm not trying to argue their positions, but does anyone have an idea of how to pull that off in Tefilin. Especially without posuling the dalet by having have the tagin of the letters below enter it?
So far this is as good as I have been able to manage.
