This is a stocking for one of my grand-kitties, Oliver. I still need to make one for Opus and one for Maestro.
This is a free pattern from Embroidery Library:
They also have a free pattern for a puppy stocking (bone-shaped):
The pattern calls for pre-quilted fabric for the back of the stocking. I chose to use the same green fabric as I used on the front (Patrick Loses' Fizz fabric) and I quilted it myself.
