OC Richard,

Sir,
The phrases "Pleated to the Sett" and "Pleated to the Stripe" are two of the most accepted phrases used in Kiltmaking.
Your phrase, "Pleating to the block", seems to be your personal phrase or perhaps the one used in your local circle.
Another phrase commonly used is "Pleating to the Line"

Whichever phrase is used, 'to the stripe', 'to the line', 'to the block', it actually refers to the same thing. i.e. using the same element of the Tartan pattern on each pleat of the kilt.
Because your term "Pleating to the block" is not used in the book is nothing more than semantics.

The book covers this type of pleating very well. It simply uses the most accepted phrase for this method of pleating.

The caution in the book, of pleating where the element used does not contain a prominent vertical line or stripe, is valid. Many Tartans if pleated without a prominent vertical element do indeed give the appearance of "The Dread Lawn Chair Effect". This effect is certainly one that needs to be taken into consideration when choosing how to pleat a kilt. Many people find it less pleasing.

Because some kilts may be pleated this way does not constitute another, separate, method of pleating.

Your "Pleating to the Block' is actually "Pleating to the Stripe". You many use your phrase if you wish, but this thread is about "The Art of Kiltmaking", 'Pleating to the Stripe" is the phrase used there.
