Outstanding! You do great work, Einseidler!
I recently found a historical study (actually someone's Master's thesis) concerning the relationship between white settlers and the native Mesquakie and Potawatomi people in Iowa in the mid-19th century. Twined goods, especially bags like those, were staple items of trade offered by the Indians for farm produce and other goods from the settlers. So, they were highly valued back in the day, and not uncommon.
It's great to see someone carrying on the tradition of making these.
Best regards,
