Hand made is when you make the item from start to finish. Not purchasing pre-made items. I don’t think a sewing machine really matters as the words are “hand made” not “hand sewn”. Fact is is not everything really needs the strength of a hand sewn item. Many stitches are mearly for looks.
If product does not go through a manufacturing belt and the item is made with great detail and attention; as well as actually touching and manipulating it with your own hands, I see it as hand-made.
Saying this, I will both carve and tool as well as use the occasional stamp. If something is entirely stamped, I am sure to tell people. Custom, hand-made, personalized, they are all different. Some people make some shitty hand-made items. They are not artisans. Quality has nothing to do with how it’s made, just who’s making it.
