Today I got an explanation on this technique. It is basically an iterative method that allows to approximate the measures until a satisfactory value is achieved; this comes to mean that you make an initial guess, you apply an operation on it and then repeat that same operation over and over, taking the result of the previous step as the starting point for the next, which will give you more accurate measures each time.

For instance, if you want to divide a segment of paper in thirds, you would do the following:

1.-Fold one side the paper into what you guess could be the right measure for a third of it. Don´t mark the folding completely, just mark the end of it so that you know where it is.

2.-Fold the other side so that it reaches the point you just marked, and mark the folding.

3.-Fold the other side so that it reaches the point you just marked, and mark the folding.

Keep doing this. In a few steps you should have accurate thirds.

Now for fiths:

1.-Fold one side of the paper into what you guess could be the right measure for a fith of it. Mark it just enough to know where it is, as I explained for thirds.

2.-Fold the other side so that it reaches the point you just marked, and mark the folding. Now make and mark a fold which is the half of this.

3.-Fold the other side so that it reaches the point you just marked, and mark the folding. Now make and mark a fold which is the half of this.

Keep doing this. In a few steps you should have accurate fifths.

… Now that I think about all these thirds and fiths, this looks a lot like the way one would tune a musical instrument 🙂

*Thanks to my friends of the origami group in Santiago de Compostela for sharing these techniques with me.*

For fiths using fujimoto origami:

No matter how bad your first estimated fold is, in exactly 9 marked folds total, you will have it folded in exact 5ths.

Pretty Neat, Thanks!

Thanks Steve! The technique is as easy as it looks and it works really well. Actually I´ve been shown another method to get the fifths, but I think this is more intuitive.

super, easy way to divide into sections. real helpful and much more better than the described ways in origami-books! thanks betti 🙂
