I am diligently and slowly working my way through a first reading of AOK and absorbing advice provided through this forum and a plethora of YouTube videos.

I am learning to sew and am practicing stitching.

I am stuck on two stitches - similar, I think, but distinct.

The AOK notes, among several, two stitches; the catch and herringbone.

I have found these videos on the Catch Stitch:

None of these seem the same as the Catch Stitch as presented in AOK.

These are videos on the Herringbone Stitch that I've found:

The videos on the catch and herringbone stitch seem very similar to each other but, as I noted, the catch stitch shown in AOK appears to be distinct from either of these stitches.

Any advice or direction or more appropriate videos would be welcome.

As always - thanks!!
