Ever wonder watching those old movies or looking at photos pre 1920's how they got their hair to be so poofy with actual rolls on the side of their head? Back in the day, the Victorians would save their knotted hair from brushes, combs etc and put them into a hair receiver. Then to achieve the perfect hairdo, they would use nests of this saved hair as fillers to make the rolls. Must have been a tough comb out when they were done!
For now, I think I'll stick to using them as a dresser ornament!
