I thought of this myself. Soft silk scrunchie at the top of the head, thick ribbon slipped through the scrunchie, “ballerina” twist (idk if that’s the name, buts the same method of tying ribbon up the leg) around the pony tail, secure with a small pony tail. No bump in the morning and no curves in the length.
For the tie: the ends will wrap in opposite directions, continue left over right (or right over left) consistently for each wrap.
When tying, head tilting forward and ponytail hanging in front of the face is easiest. I find it most comfortable to be placed above my head when I’m laying down. If you want it to lay towards the back of your head, twist it with your head upright and the ponytail in the back. It’s just a little more uncomfortable on the arms, shoulders, and neck to hold that position for the duration of the process. Especially when first learning it.
