I want to grow flax for linen

I have the idea that at some point I will grow, harvest, process, spin and weave some flax. No more thoughts than that just yet. Working with nettle seems to be somewhat similar. A lot of people doing this are super into historical reenactment things. I am not, more interested in the sustainability aspect, ownership of my own clothing, slow fashion.

I bought a little bit of prepared flax to have a go at spinning it without all the rest of the process. Have not yet done it.

Here’s a bunch of resources I’ve gathered about the process:

• this dude doing it in northern england
• Allan Brown seems to be a UK expert in this kind of thing, here’s a video of him
• someone’s video going through the whole process, including some books they recommend. They are from california, and grow tightly on their balcony in raised beds.
  • plant the flax seeds kinda close together so it grows straight up
• another group of americans doing it, explaining most of the bits of the process.
• someone doing something similar with wild plants including nettle and milkweed, broadening the idea of what can be a fibre plant (in the US).
• spinning flax, and how to dress a distaff - flax fibre is a pain and tends to chaos - re-combing it might help, as does working with damp hands. Spinning from the fold (directly or from rolled up ends on a distaff) probably works well.
• This guy grew a tiny plot and parts 2, 3 (scutching knife) and 4 (hackle)
• this person retted some and shows some nice photos
• This person is kinda near me and has a bunch of short videos showing the different stages of retting (also kitty!).
• JillianEve grew some. She’s in the US somewhere, and had a bunch of storms. She also planted some nettle (?!) (follow-up on the nettle situation). Recommends some books

questions:

• where can get flax seed in the UK? this video suggests <www.flaxland.co.uk> and <www.wildfibres.co.uk>, and to make sure its a special type for long fibre, not for food seeds.
• is there a history of flax where I’m from (cambridgeshire currently, yorkshire previously)?
