Sewing on the bands

I have now knit the bands for the front of the cardigan. Sewing the left one with a serpentine stitch went well. I have acquired a new skill.

If you look closely at the green plastic needle, you will notice that it has a ball rather than a sharp point. It moves around the yarn, rather than pierces it. I picked up a pack of them many years ago for a Girl Scout craft project. Remember sewing cards?
