I see diagram and words, still confused. Last paragraph: "Stack the two lengths of fabric one on top of the other, both face up.", since it's a single piece of fabric, how can you get the lengths on top of each other, both facing up? I can get them on top of each other with 1 up, 1 down, but not both going one way...

I see the diagram and his "simple formula", but I still don't get it. Would love to see a photo tutorial if someone has one!

Try this! Get a sheet of paper, say 8 1/2 X 11.
Draw a diagonal line from the top left hand corner to the bottom right hand corner.
Cut on the line.
Now take the left side of the paper and move it upwards about 2 inches.
Take the right side of the paper and move it downwards, and then place the 2 pieces next to each other.
You will see a small triangle on the top left and bottom right.
Cut these triangles off.
You will note that now the paper is wider.

The same with hold true for making your fabric wider. I have only done this method with a crib quilt or a small lap size. You will need more material than the length of the quilt top, say 1/2 yard.

I wish I could do it with pictures. Maybe someone can figure out how to do it via my directions and will be able to post pictures.

Try it with paper first. Actually, the first time I did it, I did it with newspaper which for that quilt, the newspaper measured half the size of the quilt. So I felt comfortable in doing it with fabric.

I think I get it now. I drew this up in PowerPoint. Is this what you mean?

Yes, that's it.

Thank you....that illustrates it perfectly. Wow, who would have thought of that?

Only an engineer would think of that!!

Great illustration.

Thanks for the website!

Is there a guideline as to how far down you move the right side piece. The visual really helped me comprehend this. Thanx!

You move until you reach the size you want. He suggests to measure it until you are happy with the size
