I have a back porch that is only open on the south side. I want to put a half wall of lattice up with a small gate to keep my dogs off the porch so it will be nice. I am a single mom now, limited funds and I don't know much about carpentry but I figure how hard could it be. I have a list of supplies (lumber) needed but don't know where to start. Are there any plans out there for DUMMIES??
