“This is absolutely perfect for threading through the Grimm’s bobbins. The wooden stick and thread both pass through the bobbins, but the stick is too wide to go through the Grimm’s buttons. So you can keep the bobbins on one end either by tying a knot in the end of the thread or by placing the thread through a button followed by the bobbins. This makes a nice challenge for children just starting to progress to the harder challenge of threading the Grimm’s buttons.”
