You can see why dew retting creates a grayish linen. The molds that melt the pectin covering away stain it.
Below is batch #3. It's a hybrid of dew retting at the beginning and most recently, wet retting. Even though the dew retting was coming along fine and I was starting to see the flax fibres being released, it was slimy and I wanted that gone.
So I tossed it back into the wet retting pool. It's been cold so the retting is going slowly. There is no foaming and swamp smell like I got with the earlier wet retting.
The constant rain keeps the water fresh. My challenge with this is how to dry it? I'll have to take it out soon and put it onto drying racks that will sit in my greenhouse over the winter. Won't dry much, but at least won't get wetter.
