Good morning, Nadine :)
I was curious about the technique so I took a piece of advertising paper which had printing on one side only. I cut the paper square, did the folding and marked each strip with a ruler. Three strips had two pieces: 1 and 1a, 2 and 2a, 4 and 4a. I had four strip rows plus one folded piece I could open up and trim to the exact width of the others which I have named 5. Strip 3 was in one long piece with irregular ends.
All strips are on the true diagonal of 45 degrees!
So, I ended up with one triangle to toss and 7 usable strips: 2 short strips, 1 extra short strip, 3 medium strips and 1 long strip.
By stapling the strips together as if they were 1/4 inch seams, I ended up with 7 seams.
With the time to piece all these different size strips, I doubt that I will use this method. I had to think too much! However this can be done. My sample size started with just 8.5 inch square of paper.
I am always willing to try new ideas and appreciate you having shared this technique. Hope you have a good day:):)
