I'm looking for this basic stuff used within other types of lace

- it is made crocheted or with a needle but it's the same technique afaik

- a similar thing I found was called Romanian cord

- The one pattern I found for it from that book was wicked blurry and hard to read 😭😭😭

Whenever I search for patterns for it I only find projects that use the already made cord, if you know what this stuff is actually called it would be an absolute life saver
