While dealing with Motif Writing, I got another idea about how to write the sign for “still form shape – screw/spiral.”
Ex. 1 below is the sign for “still form shape -screw/spiral” which is used now. It indicates a screw or spiral in any direction. Ex. 2 is my proposal for indicating “still form shape – screw/spiral” only to the left. Ex. 3 is my proposal for “still form shape – screw/spiral” only to the right.
