I always wondered about this, do the shirtmakers have a bunch of pre-made cuffs that they wrap with the material you want, or do they make them seperately for each shirt. And, if they make them seperately, do they end up being of a lower quality than the ones that they are used to making?
I don't think you quite understand how a shirt is made. Cuffs and collars are cut along with all the other parts of each shirt and sewn into what they are. Except for the largest operations, there are no "parts" kept around to be used when a shirt is made. For example, a cuff consists of two pieces of cloth and one piece of interlining. These three are sewn together and then "turned" (somewhat like turning a pillowcase from inside-out to rightside-out). The resultant piece is then "topstitched" on three sides and, finally, attached to the shirt sleeve. The same basic principle applies to collars, although they are a bit more complex. To respond to the remainder of your question, there is no real difference between a 3-Button cuff and a 1-Button or 2-Button cuff except that it is usually a tad longer. There should be no change in quality ... even if you are going to a 5-Button cuff. With the exception of the two which are obviously more complex, the sewing of all of these is basically the same:
