doesnīt the place you took the class at sell them? Iīm going to take a class in a few weeks and the place that organizes it is a tiny fabric/yarn store. And hidden in one corner they sell small packages of felting needles, nothing else felting related though... Actually Iīve found that almost all local yarn stores have felting needles tucked away somewhere and the only way to find them is to ask

there are lotīs of places online as well, like

I know some Canadian sites have color coded needles eve, so that you can tell which size youīre using, but I canīt find any right now..
And then there is ebay of course
