Sea turtle needlepoint patterns

A sea turtle seen from above, swimming, its heart-shaped or oval shell covered in plates, drawn in several styles.

The turtle is mirrored in outline, and the plates run in a row down the middle and a row each side. All are four inches square on 18 mesh and can be made round, and many are marked intermediate. The plates are divided by pale lines two stitches wide, so count those lines first.
