Stitching is more than 'just'sewing, I think. And in this world, dominated by internet activity and computer games, handcrafts like Stitching are being pushed to the sideline.
I think it is important to preserve handcrafts, because this 'seeing with your hands' is important for the flexibility of our minds.
My father used to say "A man who cannot do a womans work, does not deserve the woman he has", which culminated in him teaching me different crafts. Those crafts, I believe, later helped me in solving problems, which otherwise I would not be able to solve.
A colleague of mine used knotting as part of his therapy of his clients. "It calms their nerves and they open up more", he said.
Nah - it's not just 'sewing' - it's the healthy practice of the stoic mind.
