The old woman went over to the open window, and the girls suddenly saw her knitwork: a fine colorful carpet, as if flowing steadily from her knitting needles outside through the window. It soon spread over the garden and the meadow nearby, stretching away to the horizon.

Dear native English speakers!
Please advise if the idea is clear here. Is the phrase understandable enough? Does it allow one to imagine the picture?
The old woman is sort of a goddess knitting a magic carpet which is actually the whole real world. Working on the carpet she develops the world, makes it evolve, etc.
This is my translation from Russian.
Thank you!
