I was speaking with a sofer today and he suggested for tying tefillin knots to use a sefer entitled Tefillah L'Moshe. However, upon searching the title, I came across no fewer than three seperate sefarim of that title. Does anyone know of the particular version in question and if it is available on Hebrewbooks.com?
PS. I presently use Sefer Ta'amei Haminhagim for tying knots, so this is more about the sefer itself and the portion wherein the information is contained.
