I made over 20 feet of grass twine!
 
 I could look at the unpalatable-to-sheep, fast-growing, course-and-tall grass taking over one of my paddocks as an unmitigated nuisance, but it's really an untapped textile/cordage resource.
 I used the twining technique in this video, shared above by Master Steward Nicole Alderman:

 I generally split the blades of grass down their center-folds, and scraped them with the back of my knife or thumbnail to soften them/break down the non-fibrous material.
 
 I made enough twine to wrap around my arm thumb-to-elbow about 13 times, and the span of my thumb-to-elbow is 12 inches. The grass was very harsh on my thumb, forefinger, and middle finger, so I recommend wearing gloves or protecting said fingers with tape or bandages to twine this kind of grass. 
 
 Here is a video of my process:             
                
            
 
 
"[6] Let the people, O God, confess to Thee: let all the people give praise to Thee: [7] The earth hath yielded her fruit. May God, our God bless us, [8] May God bless us: and all the ends of the earth fear Him." (Psalms 66/67)
