Hi! I'm offering 100% linen (flax) yarn from Belgium on my website flaxerella.com
I have really thin linen thread and thick linen yarn. Natural, white, dyed ...
And I also offer spandex/lycra fiber: almost invisible cobweb lycra to add elasticity to your projects and help with keeping the shape.
You can find me on Ebay or Amazon under name designerjourney.
