First find the total number of blue sequins: 6 rows * 8 sequins/row = <<6*8=48>>48 sequins
Then find the total number of purple sequins: 5 rows * 12 sequins/row = <<5*12=60>>60 sequins
Then find the total number of green sequins: 9 rows * 6 sequins/row = <<9*6=54>>54 sequins
Then add the number of each color of sequin to find the total number of sequins: 48 sequins + 60 sequins + 54 sequins = <<48+60+54=162>>162 sequins
