Also, one turtle is a gift for one of my recently adopted nieces (adopted in the sense that I decided I felt like their aunt). I got creative when I made the shell for her turtle. She likes Pokemon, so I will include a tutorial on how to make a Pokemon turtle shell.
Supplies:
red fabric
white fabric
black ribbon or black fabric strip
black fabric scrap
lining fabric
coordinating thread
Using the bottom shell template, cut a piece of white fabric that is half the oval plus a 1/2" seam allowance. Repeat for the red fabric. Place the two pieces right sides together so that the straight edges match up. Sew Along the straight edge. Press the seam to the red side. Place the template on top to make sure it is the right shape. Trim if necessary.
Cut two 3" circles from the black fabric. With right sides together, sew all around the circle with a 1/4" seam allowance. Do not leave a gap. With your fingers, pull the layers apart in the center and cut a small slit. Use this slit to turn the circle right side out. Press.
Now cut two 2.5" circles from the white fabric. With right sides together, sew all around the circle with a 1/4" seam allowance. Do not leave a gap. With your fingers, pull the layers apart in the center and cut a small slit. Use this slit to turn the circle right side out. Press.
Finish the top and bottom shells as described above.
