If you have to pick up long lengths of wood from the lumberyard, throw a spring clamp in the back of your vehicle. Use the clamp to attach the warning flag to the end of the protruding lumber.

The procedure is very easy to understand and follow for anyone with a little woodworking knowledge. Make sure to collect all the items you need before you start with the project. You may even ask Tracy your queries directly in the comment section of the tutorial post. Or you can ask them here. Either way, I hope that you manage to build this one nicely.
