The poem takes familiar proverbs and turns them into a small set of instructions. "A stitch in time saves nine" becomes nine stitches that hold Time together, and the speaker tells you to bind it like a book, with waxed thread and a bookbinder's needle. Once that's done, other sayings spring to life: eggs hatch all at once, a swallow lands on your hand, two birds call from a bush. Even the wished-for horses arrive, thundering down from the mountains.
The tone is playful and a little dreamlike. The speaker sounds like a calm guide, offering a fairy-tale reward for patient, careful work. The images are bright and generous: a red morning sky opening roses, a summer twittered into being.
Then the last line shifts things. "Choose one and look in its mouth, but don't believe a word." That nods to the saying about not looking a gift horse in the mouth, and it adds a wry warning. The poem seems to enjoy wishes coming true while staying wary of anything that sounds too good to be true.
