You've done a whole lot of work and its like YOU wanted it, outside and in. You have the right to be proud of your install. That represents a big step in your independence from a fixed place to stay. I'm thrilled to see how it went from the first tear out pics to now.

Really shows what a determined person can do with patience and some tools. Really a good photo-journal for us to watch your progress. Excellent!
