It can be quit difficult to turn small parts right side out, like arms, legs and tail of a soft toy. When you use a chopstick for this, it will become much easier.
You need to push the part over the chopstick like on the illustration below. You pull the fabric over the chopstick with your fingers.
A chopstick is also very helpfull when you want to put stuffing in small parts, like arms, legs, tails etc. Take small bits off stuffing and push it in with a chopstick.
Instead of a chopstick, you could use the back of paintbrush or the back of a crochet hook.
