This elastic comes in 1/8”, 3/8” and 5/8” widths. The one most commonly use for headbands is 3/8", but some like a thin 1/8" headband, especially for babies. Some elastic is made with silicone strips in the back. This is useful if you are concerned about the headband slipping.
Beware of making the headband so tight that it would be uncomfortable.
Look for a fray-stop spray at your local fabric store and spray both ends of your elastic. To seal the ends with heat, quickly pass the ends through a flame to singe them.
Be careful not to burn yourself. The glue will be very hot. Wait 30 minutes for the glue to dry completely before wearing the headband. You can also sew the ends together. Thread a needle with a thread that matches your elastic and put a few stitches through the overlapped ends. Tie a knot to secure the stitches.
Once you secure the ends, you can put the headband on and slide the decoration into the proper place.
Be sure to line up the pin so that it is not lopsided on the headband.
It is a good idea to place this flower over the seam to cover it and give your headband a nice, clean look. Allow 30 minutes for the glue to dry.
Now you have a hairband which can hold any decoration you have on a clip by sliding it through the loop and clipping it in place. You can also glue flowers or other decorations to a clip if they are not already fixed to one.
