Source for machine washable wool fabric by the yard?

EDIT: actually, I realize now, that both these fabric will "felt" if you machine wash them. Which for backpacking clothes, is not what you want.

Wool "interlock" can go through the washer. It may not be light enough for what you want

Wool "crepe" is lighter but I'm not sure if it's machine washable.

I know both are available in the US. But I forget where.

Neither are probably dead-on in terms of what you're looking for. If you search these terms it may turn up other weights of wool.

Or you could give these a try for the medium-weight item at least. Check on Etsy to see if someone is selling them in small quantities.

[During my hiatus from backpacking I learned a lot about cloth diapering. These wool fabrics are used for covers. In other words, they're super soft. And have other magical properties.]

Thanks for the suggestions- I did come across this wool jersey fabric at 7oz/yard (approx 200 grams/yard) which claims to be washable-

This is where my knowledge of the fabric stalls out because I don't understand what makes this washable while the wool interlock (97% wool 3% spandex) can't be. I am fine with doing a cold wash, just don't have time to wash by hand.

The rain shed has some. I think 5 oz.
