יהוה = Yahweh in Hebrew.
1 Chronicles 16:11
Seek the LORD (יהוה) and His strength; Seek His face continually.
In shadow knitting you have to search for the pattern, you can only see it at a certain angle. When you look at the scarf head on it looks like a plain striped scarf.
Seek the LORD while He may be found; Call upon Him while He is near. - Isaiah 55:6
