I talked to Sara before and I'll be helping with the community center. I already work with the animals on Wednesdays. I can make basic tables and chairs, and other carpentry projects like framing and the like. I've worked construction before so I can do things related to getting a building up but not the wiring or plumbing of it.
I don't know anything about septic systems though.
Also, Ruby let me know there is communal fabric and a machine. I can sew basic clothing and mend torn clothing so I can help with that on the side if Briseis and Ruby get overwhelmed or you want me to mend something for you at night while I'm on watch.
