Hello again, and thank you all for the warm welcomes! I appreciate it, and I have to say that if I had not been able to lurk on some of your Lily blogs during the past few months I don't think I would have gotten to the point I'm at now!
OK, I will go ahead with the porch foundation and porch roof before attempting the main roof. I can see the point that the porch foundation will affect the sturdiness of the house -- and I've had some warping issues already, so it could probably use any help it can get.
Here's a picture of where I'm at right now (please excuse my messy basement):
Oh, and I am not building the stair hand rails and balusters (interior) -- daughter's little fingers aren't all that nimble, and I know she'd be upset if they accidentally broke off.
I bought a little nursery furniture play set, and I think I will put a picture of the Lily with it for her to open on Christmas.
