Israel Regardie was adamant about the idea that Neophytes should be able to draw the Hebrew letters to the best of their ability. To this end he provided our temples with Hebrew practice sheets for students. Regardie suggested that the student use a calligraphy pen to draw the letters. For the sake of ease and simplicity, we suggest that the Neophyte use a writing instrument called a lettering pen or calligraphy marker. This type of marker has a felt tip which is wide along one edge. The marker can be held with the wide edge of the tip perpendicular to the lines on the practice sheets. The upward/downward and left-to-right movement of the marker across the page will result in the thin vertical lines and the thick horizontal lines.
Always remember that the Hebrew letters are holy symbols and as such they should be carefully and faithfully rendered. The letters are all the same height except for Lamed (which is taller than the other letters) and all of the Finals (except for Mem), which have tails that extend below the other letters. Mem Final is distinguished by being the only oblong letter, thicker in width than in depth. The general idea behind the Hebrew letters is the square formation. The letters should be drawn repeatedly until the student is proficient in recreating them.
