In Photoshop, how does one create the below single-line zig zag effect, per the instructions? Every time I have completed a work path, it will join one end to the other, so the stroke I apply after making it into a selection will always be of a looped shape. (N.B. The grey line above the jagged one is the bottom edge of a rectangle that was created in the previous step. The zig zag line appears to be on its own)
Thanks very much for any help.
There's a trick... it's not an open path. It's a closed path with 3 sides outside the canvas.
By making 3 sides fall off the canvas, their edges aren't seen, the path is closed and you can then apply layer styles to it.
