Once or twice a year we go to the Museum of Kansas History in Topeka, https://www.kshs.org/p/kansas-museum-of-history/19578
On Kansas day we get to meet a huge crowd of kids from across the state. 1,2000 to 1,400 kids come through, Mostly they are grade school and Jr. High kids. We pull in extra helpers to meet the demand
Some kids walk on by, many stop and are fascinated. Parents and teachers sometimes make a seam if they happen to hit at a slower time. Some kids swing by and do it a few times. The sneaky ones go to a different operator each time. Because of time limits we can't do treasure pouches, we just have them sew a seam across a folded piece of fabric. Some get creative with that and have done a monogram.
