I will save all my large Stalks... Let u know when I have a good collection... now I'll go learn to spin me some wool!
Hahahaha Knitting never worked out for me... but saving the planet one stalk at a time - is very appealing! - makes me wanna Learn New Stuff!
If you'd like I'll set my flax wheel up and take some images so you could see it. But you can spin wool, hemp, cotton, flax anything on a decent spindle or a not decent spindle LOL. We did everything on spindles for thousands of years. Low tech and very dependable. Oh but the wheels are just delicious works of art. I have a couple large production wheels that are just wonderful to feel move with you as you make thread. Very soothing type of work.
This is a good place to start for general info on it and lots of videos etc....

Oh and I spin mostly fine for weaving and lace. For example this is a merino fleece I just purchased:

After you wash it it looks like this:

Since this is a knitting project I'm carding it. If it were for weaving I comb it.

You take the rolags to the wheel and you spin them at 1/2 the diameter of the fiber you are going for. In this case I want roughly very fine so there ya go:


When I finally have enough plied and set this will be knitted into the shawl below.

*shawl isn't mine but the rest of the images are mine and my equipment.
