She would have bought this made up and then embroidered the stamped design. Remember this was before television...so she'd sit a few evenings...sewing on this just so she could feel pretty working around the house. Of course it was an apron, which meant it got dirty and stained, so she needed several...because you wouldn't want to be seen in a worn out old thing. But when her apron was fresh and new she's have pride of having made it herself. Must have brightened her day.
