Fill the sock with cotton, leaving the ankle area empty. Fold over the empty ankle and hot glue it to the back of the sock.
Hot glue mini pom poms onto the sock to make the eyes and nose. Use a fine tip black marker to draw on the mouth, whiskers, and other details.
Now cut ears out of felt and glue onto the head.
In the same way, cut felt arms, legs, and a tummy for the cat and glue in place.
Finally, cut a tail out of felt and glue to the back of the sock. Repeat for different sock buddies!
