“Even a blind squirrel finds a nut now and then” and that’s my motto for these DIY videos. I am not a professional in most areas covered in these videos, just an average guy trying to save money by doing things on my own. Obviously I only post the videos if I was successful, and so I hope I can help you out.
Ask any questions you have in the comments, but just know I don’t really know anything & just figured it out along the way. If you know anything about the project in this video or have experience yourself, please by all means comment and tell me what I should have known or done differently!
