Fine Elastic thread is helpful not only to knit into garments, but also if things are a little too big. Be aware this thread is super fine, like gossamer, almost invisible, but have taken a threaded it through a cuff or back of the heel of a sock after I have knit it, which is fiddly yet do-able. But this elastic thread is best knit in, held with your normal yarn, where you want more elasticity.
This elastic thread is exactly what it is supposed to be - invisible carrying elastic. That doesn't make it necessarily easy to use, though, and my learning curve was steep. I used it to make a scrunchie more springy and to make the wrist portion of gloves tighter so it hugged the skin.
