Here he is ironing out the 2 1/2 by 7 inch strips you need to begin. He cuts everything but 2 1/2 by 7 inch strips- so keep an eye on him and remind him often of the correct measurements. I find it helps if you cut the 2 1/2 and he cuts them into the 7 inches.
We spent yesterday making lots of examples with notes to jog Dear Daddio's memory while he is trying to explain what goes where and how it gets there. Notice I put out the 6 1/2 block that is used to square things up. He keeps moving it but here is the proof I put it out where it belongs. I also have an example of how the charm squares should be ironed to make the creased sewing line. Don't let him do them all in advance because the crease doesn't stay sharp enough to see. Don't ask me how I know this.
