Pull rubber band in waistband
Who has not ever pulled an elastic and in the end you did not know how the end is sewn together, without you get an 8-in, so twisted sewed.
So today I came up with the idea to make a line at the beginning and end on the same page with a white rubber band.
If he is to be pulled into a white clothing, you can also make a line with a pencil. He does not bleed.
With a black rubber band you can make a line with the tailor's chalk / chalk at all, or if you do not have that, pull a thread through. The loose ends should then be on the same side. You can also pull through a longer thread and then take it as sewing thread.
For threading I take a safety pin.
