I am restoring this hairpin doily for a friend. She inherited it from a relative and wants to keep it for her daughter. The knots closing a few rounds have come undone so I used invisible thread to mend the rounds. I washed the doily and started pinning it out but 50 pins are not enough. So tomorrow I will stop at wool-tyme to pick up more pins. The outside round wants to bunch so I'm going to pin each section to get a smoother result. So maybe I'll buy 2 packs of pins.
