Haha, my mum who is an upholsterer has so many cool tools like that! I used to make fabric buttons all the time when I was little.
But becuase it is like crazy industrial strength, a bit like this:
but it had a handle coming out horizontally, and you had to wind it downwards and then slowly release it up again, to add pressure to the macine. If you let it go when it was the furthest down it could be, it would just spin around the rod it was attached to and be crazy powerful. When I was nine and so and hanging out in my mum's workshop, I was sitting around making buttons with pretty fabrics and managed to let it go when it was done with the button, and it smacked me RIGHT in the head. Fuck me, that was painful.
I also stapled myself in the hand with my mum's super exciting professional staple gun when she was working from home, when I was 4.
I think the lesson to be learnt is that I am not good around the industrial sewing stuff. It is nutty. But also very fun! I should take pictures of the fun stuff my mum has in her workshop. She has like 300 000 different needles, fabric samples, thread rolls and things like that.
