Measurements:

Before felting - height: 35” (89cm) width:11” (28cm)
After felting - height: 14” (36cm) (including flap) height without flap: 7.5” (19cm) width: 9.5” (24 cm) Depth: ¾” (2cm)
This was after 3 washes in the machine for a thick sturdy texture.

Knitted on straight needles and seamed before felting, this is easy for beginners.
