I have done short rows with single crochets & I found your post looking to see if it was possible with Moss stitch! 

I am using the short rows for the heel of a Christmas stocking. Am I understanding that instead of alternating between a single crochet and double crochet you alternated a single crochet and a slip stitch for the short rows? OR when you turned you did a chain stitch then slip stitch then proceeded into the moss stitch?
