I helped Girl Scouts this summer - two all day classes, with 12 and 16 girls respectively. We made several things on the machines. There were 5 available. The leader did not know much about sewing and there were no other adults present, so it all fell on me. Some of the girls said they could sew - and they could not. The scouts were very happy with my volunteering - and I am sure they will ask me again. We did make a t-shirt bag and a scrunchy scarf, with no accidents. I told the leader that if there is a next time (and I am sure there will be), I will hold a tutorial for all the girls to understand the machine and safety issues. I will then give them paper with lines on to sew without thread to practice hand/foot coordination. One of the girls was a senior scout, going to college this fall. She did know how to sew - but had a problem. She said her machine was not working - I suggested she turn it on!
