Vintage Sewing Pattern Collection

Purchased as part of a larger vintage collection, I truthfully do not sew enough to know anything about sewing patterns and am unclear how these work. There are patterns in each envelope, and I assume they are usable, but I would not know if a piece is missing. Dates printed on patterns are pictured, placing this collection from the late 60’s-early 70’s. Buy more and save! Add 3 items to your bundle for 20% off your order.
