A common saying to describe a woman who is lazy, about how to measure the length of thread when sewing something.

"Stupid wife recognizes long thread", "Stupid wife recognizes long thread", "Lazy wife recognizes long thread", they all can recognize a needle by putting the thread through the needle hole. I don't know if this is the word recognition. In sewing Sometimes lazy women would leave the thread very long in order to reduce the number of stitches. In fact, when the thread is longer, it seems that the stitches are saved. However, when sewing, it takes a long time to pull the thread before sewing even one stitch. The thread can easily get tangled in the next stitch. But a diligent woman leaves just enough thread to let her arm swing naturally. The length of thread that can be tightened at one time is more efficient. Call your wife a mother-in-law. It's okay, there is no completely fixed way of saying this saying
