There are a lot of really good uses for 'invisible' thread (and it comes in clear-clear and a dark-clear for use on darker fabrics). Having said that, let me add a word of caution. It is like thin fishing line, it is hard to break. So, if a thread comes loose, it can stay put and wrap around tiny baby fingers and toes and strangle them. I never use this thread on anything I am giving to a child.
