stuck on the pillars and getting really annoyed. got the bowtie one but none of the others walkthrough has helped but I have done exactly what it has said and still nada help me plz.

OK I have read the walkthroughs and they all give same advice but I draw and draw and still can only get wedge one to glow. I have tried drawing big and small still nada. I have done everything I need to to get to this point yet still nothing. I have looked a pictures and maps. I even tried going pillar to pillar drawing each symbol and nothing. I am really getting annoyed. Any advice from anyone?
