Another way to zig-zag

I've never loved the way zig-zagged seams looked. Even after sewing it can still ravel to the stitches. But my sister gave me a new idea for zig-zagging seams - instead of doing it in the middle of the seam allowance like so...



...she suggested I try doing it on the edge, as it works the same and looks much nicer.



And now I think I'm addicted! Try it out; you won't regret it!
