This one in Portuguese - my translation left something to be desired, but the pictures are fairly self explanatory. Direct link to pictorial ~ crochet petal edging. Beautiful, but wouldn't want to have to cover a vast area with this stitch.
Crocodile stitch shrug cute for a little girl. Just start doing rows that'd be long enough, make it about 7 rows, one row skipping 4 scales where arms go, then 3 more but adding 6 instead of 4 where the sleeves go.
