Tiny Eggs

Elected to work all rounds in tapestry crochet to make a stiffer fabric.

Elected to work the last row as:
(sc, ch 1) x 2 in each stitch around vs the crab stitch, as written. I found the crab stitch to cumbersome for the yarn I was using.
The (sc, ch 1) x 2 around created a firm, rustic edge.
