Others compare "knitting a sweater" to "an almond outside the wall". As the latter part of the sentence, there are various verses, such as "asking how the world is doing, knitting a sweater is committed to life and death" or "suddenly looking back, that person is still knitting a sweater ..." What is knitting a sweater? In fact, "Knitting a Sweater" is a song with funny and sad lyrics, which makes knitting a sweater the object of repeated spoof and creation.
