I just added some Flax Top to my inventory at Wind Rose. I've been wanting to try spinning flax myself, so I thought I'd get enough for the shop too. This flax is very soft and fine. The staple length is approx 12 inches which means it would work well for doll hair. There are some very nice YouTube videos on spinning flax. Here's a couple of my favorites. Flax Spinning and Spinning Flax Into Linen Thread.
