My husband and my two children at home and I went to Kenya recently. He was teaching a class, so I had some free time.
My daughter and I walked around one day and I took some pictures of a few small shops where they make clothing. There was a larger fabric store in a mall, but this appears to be how most clothing is made. You walk into the shop and choose the fabric, then they measure you and they make it from the fabric choices they have.
I asked one lady if I could take a picture of her lady sewing, but she told me I could only take the machine. The shops we went into only had people using treadle machines. One shop had 3 people using "Butterfly" machines--all treadles. The one I got a picture of had a Singer treadle. Interesting.
Anyway, this is for your educational pleasure!
