Ok so I found 2 free patterns for turtles. This first one is a delicate turtle pattern. Quite nice... :)
This next pattern is from "Deb's Crochet", you can get the link below,
She has a nicely written out pattern so try it! You could try changing the color of the shell to make it look different as well :)
This turtle I wanted to show you because it's a 3D 2D applique :P ya what does that mean :P The shell is on top of the feet and head! Just like a real turtle! ^^ It's a nice idea i think it looks pretty cute with the bead eyes.
