@Huma0 Years ago, I was sitting at my kitchen table sewing something on my domeestic machine, carrying on a conversation with a friend who had come over to visit, when she suddenly said, "Oh- you sew really slowly. Maybe that's why everything I try to sew comes out so bad."
Well, I don't sew slowly, but I guess she just presses down all the way on the pedal at full speed without trying to keep the fabric lined up and so on.
A lot of people started to sew without learning the basics of how the machine works, how to adjust tensions, how to clean it, etc. I've had friends ask me to take a look at their machine because it's not working properly. I'll find a wad of thick matted fluff under the needle plate, the needle in backwards, the tension maladjusted, or the machine needing oiling. When I ask when they last oiled it, they look at me blankly- they thought that was something a technician does if you take it in to be worked on. Or I'll explain to them that the tension isn't correct and they tell me they're scared to touch the tension dial.
I hired my niece, who had a bit of sewing experience to help me out at one point. Her stitching was so crooked! I asked her where her eyes were focused when she was sewing. She thought I was being sarcastic and laughed, but I told her no, it was a serious question. She thought for a minute, and said on the needle. I told her there was no need to look at the needle, it goes up and down all by itself when she steps on the pedal- her eyes should be on the edge of the fabric in relation to the presser foot. Once she got that, her stitching was all nice and straight.
It definitely takes patience to sew- those who are focused on the finished product without wanting to take time to focus on the process, or who don't know how to adjust various parts of the machine or troubleshoot get frustrated.
But I doubt that patience is your issue- all that furniture refinishing you do requires good prep and detail work and patience.
I think there are just some things we aren't cut out for. I absolutely hate doing any type of carpentry. I even hate sawing a board or hammering a nail.
