I love the control that I have while treadling, a slower pace. The treadling sound has a way of soothing me, a calming effect. It's like the treadle is talking to me; telling me that it's okay to take life slowly.
As Charlee stated, the stitches on these vintage machines are beautiful!
As Nancy stated, the machines will out live us.
I also look at these exquisite machines as mechanical art that I can use to make quilts.
I just wish some of my machines could talk because I'm sure the stories that they have would be a delight!
