Oysters needlepoint patterns

In most, one oyster on the half shell, seen from above and upright: an irregular teardrop shell with a rough, frilled edge.

It is drawn in more than one style, in some with a lemon wedge beside the shell. All are four inches square on 18 mesh, and some can be made round. Where the shell is shaded in close colors, compare the threads first; most are marked advanced.
