lot of 2: 1 youth & 1 adult (black) amish bonnets. Purchased from Northern Indiana amish families. Strings ARE attached. Smallest 5-1/2" front to back and 15-1/4" string to string. The other is 5-1/2" x 16-1/2". It would be best to measure. I am guessing the small one fits 8-12 year old, then small adult for the larger one. Questions welcome. Thanks for looking. Bonnets are held on by straight pins, double tape or bobby pins.
