Mary Corbet, owner of Needle ‘N Thread, has posted several embroidery tutorials on YouTube. All of the basic stitches are there, but she also demonstrates rare stitches as well. This is where I learned about the colonial knot and the oyster stitch, which I decided to use to fill in the fins of my cuttlefish:
During my learning process, I discovered that if the colonial knot is reversed, a different stitch is formed. This other knot is much smaller and doesn’t have the roundness of a colonial or french knot.
If you have seen this alternative stitch, please let me know what it is called.
