The Letter Dalet has 2 main parts. There is a roof and a leg. If the heel which sticks out on the top right corner is missing, the letter is still kosher. We want there to be a heel sticking out so that the Dalet is distinct from the Letter Reish. The roof should be 3 kulmusim long.There should be one Tag at the left end of the roof. (This Tag should not be on the very end of the left side, nor be made too large, because it can be a problem.) The leg should be slightly shorter than 3 kulmusim.
