Sleeve: chain 46 (or enough to wrap the long dimension of your brick with 2 cm ease). Work moss stitch (sc, chain 1, skip 1, alternate each row) until the piece is tall enough to wrap the brick's short dimension plus 5 cm for tucking. Fasten off, leaving a long tail.
Wrap the brick in the sleeve like a jacket. Sew the open short ends together under the brick, pulling the yarn firmly so the sleeve does not slip. The brick is now completely enclosed.
Head: with black yarn, magic ring, 6 sc. [6]. Increase rounds to 30 stitches over 5 rounds. Work 3 plain rounds. Insert the amber safety eyes between rounds 4 and 5, about 6 stitches apart. Decrease back to 6 over 5 rounds, stuffing the head firmly before closing. Fasten off.
Ears (make 2): chain 4. Row 1: sc across 3. Row 2: decrease once, sc 1. Row 3: sc2tog to close. Fasten off with a long tail. The ear looks like a small triangle.
Tail: chain 25, sl st back across to create a rope. Coil or curve it before sewing to the back side of the brick sleeve.
Sew the head to the top front of the brick sleeve, ears to the top of the head, and tail to the back. Embroider white straight stitches for whiskers and a small orange or yellow nose knot above the mouth line. The safety eyes should face forward.
