There as been talk, recently, on one of the groups I belong to, about boat shuttle and how to throw them without them "nose diving" to the floor! I was winding my own pirns for my boat shuttle when I realised why some people, usually beginners, have problems with their shuttles, so here I'm going to show you how to wind your bobbins.
Or if you make your own paper ones, I'll show you how I do it in a later post!
First of all build up a small mound of yarn at one end of your pirn.
Now move your yarn across the pirn to the other end and build up another mound.
Next, fill the space between the two mounds with yarn moving backwards and forwards across the pirn so that it fills evenly.
