The very last mitzvah in the Torah is to write a Torah Scroll.
Historically, not too many people have had the wherewithal to undertake such a project, as a Torah is hand-written by a sofer (scribe) on parchment with a quill pen, and contains 304,805 letters, a very expensive undertaking!
It is an honor and great mitzvah to participate in the writing of a Sefer Torah. By endowing a word, verse or Parsha for yourself, your children, your family members or friends, it is as if you have written your own Torah Scroll.
By contributing towards the writing of this new Torah scroll, you are fulfilling this important mitzvah.
This project is unique in that Lithuania was world famous for centuries for the study of Torah!
