If you’re lucky enough to have a sewing machine with a blind stitch option, you can finish your projects with an invisible hem. Let me show you how I do it for my pillow case dresses. I used a dark thread for this dress only so you could see what I did. Otherwise I would have used a white thread, and it would have been nearly invisible.
Turn the dress inside out. Iron up ¼” of the hem.
Then I turn up another ¾” of the edge, iron and pin.
Now I flip that pinned hem under, and leave about 1/8” peeking out. Hopefully my photo will explain better.
Pin in place.
Now it’s ready for sewing. Find and attach the presser foot for sewing a blind stitch.
Select the blind stitch option on your machine. Mine is option 11. Practice with a scrap piece of fabric to determine which stitch length and width settings work best for your machine.
Line the fold up against the blade on your presser foot. I have 2 pictures that will hopefully show you what I mean.
You want the machine to just barely catch the fold. I’ve got mine catching more than I normally would so you can see it. Here it is finished:
Finished hem. Use a smaller stitch width than I have for this example, and a matching thread, and you will be “blind” to the hem.
After you’ve used this method a couple or so times, it will become second nature.
Good luck and have fun!
