Crabs and lobsters needlepoint patterns

Crabs and lobsters seen from above: a blue crab, mirrored, with a sharp spine at each side, and a lobster with its claws up and its tail down.

The crab's shell is much wider than it is deep. Both are drawn in several styles. All are four inches square on 18 mesh, and some can be made as a round ornament. Legs and antennae are thin lines, so count them first and fill the ground after; each page gives its level and its thread list.
