Have you ever wondered how your sewing machine works? This was a really interesting video showing how the thread is picked up from the bobbin and it makes a stitch. It might help you understand your sewing machine a little bit better.
I have been working outside and as soon as I get things under control, I will start sewing again!! Soon, I hope, I am missing it!!
