These fuzzy stickers are so cute and great quality. They stick to the violin easily to provide a soft spot for the thumb to sit for little beginner violinists. Children will love petting the sticker lightly with their thumb and when the fuzz wears off the teacher knows that they have been squeezing too hard! I tell my students that they would never want to squish a brand new puppy or fuzzy panda. These thoughts really help the children to learn proper technique on the violin.
