Hey hey! I wanted to let you know that I opened a small mini at Garner next to the creek east of the castle. The building is a fulling mill, where wool directly cut from sheep is washed and cleaned in order to remove oils, dirt, and other impurities. I attached a couple of images below to illustrate how the machinery works, however if you still need a bit of explanation feel free to ask or look for more references (the wikipedia article about fulling is ok). The building is requiered to have a main station where wool is cleaned and thickend (the watermill itself), a small tenterground (area used for drying newly manufactured cloth after fulling) and a small storage building. If you'd like to give it a go, make a test in your plot and upload it here on the thread!
