I have found no machines (built or destroyed) in the swamp for processing Ironsilk.The closest plots are in Lerena soplayer made machines won'thelp the situation any -and it's a long run from Lerena. There is even a woodshop right next to the Thornwood in the swamp too!
All other resources have machines or plots near by to make crafting easier. How about showing the clothworkers out there a little love.
