Sewing Two Handkerchiefs Together ? But Why?

In the 1950's and 1960's in participating stores if you spend so much money they would give you green stamps and books where you can paste them and redeem them at any participating store.

My mom eventually had enough green stamp books to trade in for a manual sewing machine which of course uses a foot pedel.

I was into magic in my teenage years:When it was my turn to use the sewing machine, I put one handkerchief over an another (same color),and started to sew  the three sides of the handkerchiefs all the way through, except when I reached the forth side. Starting from the left I only sewed part way, then I started from the right side, and again sewed only part way which left a pocket between the two handkerchiefs to insert objects.

Making sure the pocket is on top ,I would show both sides of the gimmick handkerchief to an audience, and would raise the bottom to the top, and would put in a small object (like an audio cassette case) into the pocket of the two handkerchiefs . I would let bottom half fall, and again I would show two sides of the handkerchief; Of  course to the audience it only look like one handkerchief.They had no idea that the object was between two handkerchiefs.

              Yes, that would make a nice sleeveless trick--lol;And never show the same trick twice.

By the way, on Netflix right now they're showing "Breaking The Magicians' Code" starring "The Masked Magician" and shows you how various illusions are done. None of which should never be performed at home. Take heart though  he will also show you how to do magic tricks which can be done at home.

Below is a 1921 silent video that shows you how to make a bra out of two handkerchiefs. But why?
