Which stitch to use?
For blind hemming, you could use E, F or G
Instead of trying to explain what you need to do, I am adding a video link....
You absolutely can use your normal zig zag foot!!!! I have a blind hem foot, but I NEVER use it.
With a normal zig zag foot, you just need to learn the width of the long stitch & then keep the stitch in the correct place. Once you are used to your machine, this is really simple & easy to do.
