I bought the Garfield from Greenleaf in 2006 and have only now found the courage to begin building it. I have no real experience building anything (except a birdhouse years ago in high school) so I'm working excruciatingly slowly and with the knowledge that I'll make a lot of mistakes along the way.
I did a dry-fit of the house a month ago and was able to get a feel for the house. It was also really helpful to just know that I could assemble it. Seeing it all together gave me a lot of confidence to continue with the project.
