Query: wonderful aid

I am learning to play the violin by myself. I saw on videos and books that some people use the tape as visual aids to learn the correct position of the notes. I decided to buy this aid rather than putting a tape for each note.It's actually a wonderful aid. It took me some extra work to place it in the right place. I had to use a tuner so that i would place the first bar in the right place. It was quite easy to place it on the violin also. I hope it will come out just as easily. You cannot feel it with your fingers when you play.I would recommend it to all players especially those who are learning without a teacher.
