PRESSURE!!!!!! That's the name of this game!! The key to lettering in the sand is very very VERY light pressure! Multiple passes!! Patience!!

If you make a mistake, it was because you were moving too fast!!

If a chunk breaks off, too much pressure!!

Now, I will say, on the cross section of a lower case t you want to go out from the center junction! Lead AWAY from any point in a letter! Examples, top of A, All points in M, and N! If you carve towards a point, it will break off! I will do an advanced lettering video covering this exact topic!
