It is two sided. I stitched the tail end with glow in the dark green thread - just like the lightning bugs. I made a pocket made of the plastic tablecloth material you can get at Wal*mart and made 6 Lightning Bug charms to store in the pocket. I also used the glow in the dark thread for the work bioluminesence and for his name and for the little message to him. It was soooo much fun and it turned out great! Next time, I would put the stuffing in a little lined pillow inside, instead of just loose inside. I used florescent green thread on the decorative stitching around the edge, and added a hidden zipper too. Thank you Yoriko for the great Lightning Bug designs!
