Just thought I'd let you know.
I just finished the third 4-H sewing project in two months. Worked with 29 members ages 9 - 21 (including two boys) who made their first ever pj pants out of cotton or flannel. Sometimes it was a struggle for them - and they reluctantly bonded with their seam rippers - but they are so very proud of their pants!
I provided 6 of the nine machines we used and was in charge of keeping all the machines going. Surprised myself at how much I actually knew - and knew enough to look online for more info for the foreign-to-me White, Kenmore and Singer machines. I was also the experienced sewist
And I noticed that my little black Singers gave the kids no problems at all. They sewed on two 221's, two 222's, 99K, Singer 774, Pfaff 1222E, Janome 4800, another simpler Janome, White and a Kenmore I could never find the manual for. Everything got at least one good cleaning and oiling.
