Olwyn Mary in New Orleans.
I attach a short length of the yarn to the ball band (two holes in the
band and secure the yarn with a lark's head knot) right above the
laundry instructions. Or, if the garment is big enough, I sew in a
fabric label with the laundry instructions. I have a supply gotten
from one of those personalized-label suppliers; I sent them text for
the otherwise-blank labels.
