Step 4: Turn the Arms Right-side Out
Take one of the sewn arms, and put your closed hemostats inside. Open the hemostats and carefully lock them onto the fabric at the paw end of the arm. Gently pull the hemostats back through the opening so that the arm turns right side out. You may need to use the hemostats on the shoulder end also.
If you pull too hard, your hemostats may slip off the fabric and pull off some of the fur, so be careful.
Use the handle of a crochet hook (or similar) to push on the inside of the seams at the paw and shoulder, making sure it's completely turned right side out.
Do the same for the second arm.
