These are the how to steps on my “mistake” knot (see post directly below or click this link and read the second paragraph). Some similarities to the knotted cable chain exist and if it wasn’t for the way that thread in the loop to the right catches the tip of the needle in the fourth picture it would be a match, I think. And of course, minus the distance between the chain and the knot, too.
It starts out exactly like the oyster stitch
(Due to the fabric (32 count) and thread there are 5 threads between the two insertion points where the needle is shown on this photo.)
Pull firm put not tight
Then slide the needle under the top portion of the stitch but not under the lower part of the stitch at the top.
Pull the threaded needle through until the loop on the right looks about like next picture shows. Now insert the needle exactly where the top insertion of the needle was shown in the first picture. Bring the needle back to the front of the fabric directly one thread down from the where the bottom insertion is shown in the first picture (Adjust this insertion point as needed for the fabric and thread you’re using. For a finer thread the same insertion point might be fine or if thicker perhaps down two threads). Catch the thread of the loop formed to the right with the tip of the needle and pull the thread from the needle under the tip of the needle as shown in the picture below.
Pull firmly but not tightly.
Now pull thread through, firm but not tight.
This is finished off as a single knot by securing one fabric thread under the last bottom insertion. But if going on to make an line of stitches then do not secure but use this thread as shown in the very first portion of the first photo. And then start into the stitch as shown there.
The top leaf is smaller just because it is worked over fewer threads than the others. The leaves on either side were worked in opposite directions of each other. I didn’t see enough significant difference to change the direction but I’m sure for some critical work that might need to be done.
If you have any question about the step-by-step please let me know about that; I’ll be happy to try and clarify or revise as needed. Thanks!
