Thanks, Schneiderfrei.... Most things I do are for hands-on educational experiences for my kids (in small quantities). The experience growing linen was interesting and fun. We found the plant to be delightful to grow. It shoots straight up and then has a pretty lavender flower for a few days. We had to watch carefully to see when it was time to hand-pull it. It wasn't bad pulling it by hand. We walked through the entire process of retting, scutching, etc. The part my kids did not enjoy for very long was the scutching and combing. It is fun to try and know about, but it is down-right work, and we had to 'hang in there' with getting it done. It is dusty and messy. But once it is combed, the fiber is quite pretty. It looks like blonde hair. My daughter has spun a small quantity, but she has other priorities with college now. We harvested the flax seed, and are still enjoying it in home baked breads.... It is wonderful, and good for you. The consensus here, however, is that we won't do it again, unless we were to come into the ownership of industrial equipment.
The hands-on experience gave us greater appreciation for those who create cloth.
I hope this is of interest. I realize it is not related to technical information on cottons for suits.
