Made of nylon it works as follows.
You push the contraption onto material.
The thread is pushed through the material lead by a "needle" while nearby, at the same time, a loop is pushed through it. The needle bends over into the loop.
When coming back up the loop fits into a crack in the needle catching the thread, breaking the needle, and pulling the thread up after the loop.
You now press again. This time (without the needle) the two threads are pressed together and a tiny plastic seal holds them together.
Voilla: a single stitch. You can put a few of these in a row (perhaps held together with some kind of ruler) to get a long stitchline. or just use one to fix that torn shirt or missing button.-- pashute, Jun 21 2021 hand-held sewing machines https://products.be...est-handheld-sewing [xandram, Jun 22 2021] Good apart from needed throwaway.-- xenzag, Jun 21 2021 Are 1/2/3 stitches enough for a button? I don't think so, but then I'm very hard on buttons, so much so that on mission-critical* buttons I replace the thread with monofilament fishing line and finish off with a dab of glue.
For patching fabrics, if you don't mind the look, stuff like RTV/silicone works very well. Squirt on a square, slap on patch, press around the edges, and wait. Fast and totally wash proof.
*waistband of shorts...-- bs0u0155, Jun 21 2021 [bs0u0155], great minds think alike. I use nylon line as SOP for fixing any buttons (and sometimes for other stitching too...).-- neutrinos_shadow, Jun 21 2021 Completely off topic but at one time the buttons of the Canadian military were edible and in an emergency could be used to make broth.-- 2 fries shy of a happy meal, Jun 22 2021 //How many did you try...?//
Many of the broth buttons were given away before the men clued in to the fact that they were not indeed of any use whatsoever in brothels themselves.-- 2 fries shy of a happy meal, Jun 22 2021 Well, I love the edible button story!
i’m not sure how your product would work being made of nylon! I posted a link to handheld sewing machines in case you really needed one! Rarely can anything be fixed with one stitch, so These little gadgets will make a couple stitches for you. I’m going to give a bun because it seems like a good idea even if I don’t understand how it works!-- xandram, Jun 22 2021 I didn’t say this idea was not halfbaked, but I actually don’t understand how it works. especially how the product can be made out of nylon! I need a bit more description to understand this.-- xandram, Jun 23 2021 It's a very elaborate stapler using plastic staples-- pocmloc, Jun 23 2021 random, halfbakery
