From the pattern:

“To keep little hands warm, make a cosy muff in the shape of a snow-covered log, then add a knitted robin and some holly for decoration. The muff has circular end-pieces for the hands to pass through, which provide extra warmth and protection.”

From the website

The hand-muff recalls the Victorian era and comes in the shape of a snow-covered yule log with a robin and holly on top. It is knitted on large needles using three strands of yarn together, so it really does keep little hands cosy and warm. For extra protection there are end-pieces which fit around the wrists. The muff measures 20cm (8in) in length and would make a welcome gift for any little girl at Christmas time.
