You'll have a board that looks like this. Now get sawing! Try to stay right on your pencil line. Some words of caution:

This is not a race. Take it slow. Accuracy counts.

Even though this is practice in scrap, treat it as if it were fine dovetails in exotic wood. You are building muscle memory here -don't commit bad technique to memory by going quickly

Stick with one saw. Get good at it before moving to another
