Do you have a list of things you know you should probably learn how to do, but the thought of them seems scary, so you just decide to take the easy way out, even though it might not be the best look? I kind of felt that way about the blind hem. And honestly? I’m not sure why I waited so long to figure it out. And, really? There wasn’t anything to figure. It’s just about the easiest thing in the world.
Garment inside-out. Do it. Figure out your hemline (for this, the original hem was perfect, so I just used that as my guide).
Fold and press. If your starting edge isn’t finished, fold it at half the amount and then fold again (like any other unfinished edge, really). Put a couple pins in parallel to the fold to hold it in place temporarily (not pictured).
This is the hardest part, and it’s not even all that hard (it’s tricky to explain, but not tricky to do). Fold your new cuff back on itself so 1/4″ of your “raw” edge is showing. Pin it in place and remove your previous parallel pins so you don’t accidentally sew over them. I don’t recommend pressing this, as you’ll just end up having to try to get that crease out later.
Refer to your user manual to determine which of your feet is the blind hem foot. Even my basic starter machine had a blind hem foot, yours probably will too. If not, ebay. While you’re there, your manual should also tell you how to set to a blind hem stitch. Your stitch will look like the picture above: a line of straight stitches broken up by one zigzag stitch.
The blind hem foot has a stop on the right side. Your 1/4″ part goes under that, and the stop lines up with the fold. Sew around the entire hem, turn right side out, and press.
The result is a secure hem without an obvious hemline. Very professional (if you ignore the fact that my tension is a little wonky as a result of a broken needle).
