For example, I've had this black shirt for years that has a tear in the hem that I've just lived with, because of my irritation at sewing. But I had the machine out the other day, so I just decided to fix it anyway.
See? The seam isn't even visible from the outside of the top, and I used the stretchy stitch, so it stretches with the rest of the hem. I don't plan to go ahead and make every garment I need from now on, but it is nice to have a machine for what I need.
