Bridesmaids edging

Edging takes time to tat, therefore I managed only to tat the first row of Bridesmaids edging.  There is another row to tat but I am just happy with this simple edge.  This pattern is taken from "Tatting with Visual Pattern by Mary Konior" with DMC white thread.  It's frustrating that after I finished this piece, certain sections look "off white".  I suspect that the ball of thread is not totally white, that's why I prefer to work with coloured threads.
