You’ve probably seen the ponytail holders that are elastic with the ends knotted together. (I have seen headbands too) I saw a pinterest post about how to make them, and looked all over for the elastic, I couldn’t find any locally so I picked up a pack with 2 to see how I liked them. They hold my hair really well.
I finally found some bifold (aka foldover) elastic it is a bit priciyer than regular elastic but I got 4 out of a yard.
They were very simple all I had to do was cut the peices of elastic to the length I needed and tie a knot.
I do plan on making them again, when I can use a coupon or find it cheaper. I will also either seal the ends with a lighter or clear nail polish.
