welcome. everyone else is giving you your measurements, I have a different bit of info. Please remember that the most experienced quilter out here still uses a seam ripper! We all make mistakes and fumble around on a project. Please don't be hard on yourself and keep it fun! If something is frustrating you, set it aside for awhile. Hopefully when you come back to it, it will make sense. If not, you will simply have joined all of us with the start of a UFO pile!
