Good question! Depends on how hard I work that day, but in an 8 hour, really focused, not interrupted day, I can make 10-12 aprons from start to finish. Now ask me how many days I actually get like that and it is few and far between!
On average I make about 4 aprons a day because some days I don't work at all, some days I spend the entire day on social media and marketing materials (like this post), and some days I spend playing and Facetiming with kids and grandkids.
All I can say is I am very thankful I don't have to punch a time clock because no two days are the same.
