As a former science teacher, I enjoy learning the “how” and “why” of many things. I find it fascinating to see how products are manufactured, especially things that are used in quilting. We often take for granted these products not realizing the many steps that are involved in their manufacture. Or, we complain about the cost without knowing the time and effort involved to make them.
This video from the Science Channel shows the steps involved in the manufacture of needles and pins. Since I just bought a package of self threading needles with gold around the eye, I now know how these were made starting with a coil of wire and ending with a precision sewing tool to use with my quilting.
