Measure the circumference of your bottle. Chain enough stitches to give a tube that is 2 cm narrower than the circumference (the yarn will stretch). For an 8 cm diameter bottle (about 25 cm circumference), chain 32.

Join the chain into a ring with a slip stitch. Work hdc in the round, placing a stitch marker at the join, until the tube is 20 cm tall. Fasten off and weave in the tails. The tube should slide snugly onto the bottle.

Cut the felt sheet into strips approximately 1.5 cm wide and 20 cm long, varying the lengths slightly. You need about 12 strips.

Tuck one end of each felt strip under the yarn tube at the base and drape it upward and across the bottle at a slight diagonal, tucking the other end under the yarn at the top. The strips should overlap and cross each other at irregular angles. A small amount of craft glue at each tuck keeps them in place while you work. Allow 20 minutes drying time. Using a glue gun for this step speeds things up significantly; if you use one, an adult should handle it.

Glue the two googly eyes to the upper front of the bottle cover with strong craft glue. Press firmly and let dry for 30 minutes before displaying upright.
