It's all in hand!

Two solutions today - Monday's blip was indeed a sea urchin but I loved all the comments, especially LadyLaLa's and Meancoast! LOL!
Yesterday's body part was the skin between thumb and forefinger - well done Snowysel for guessing correctly!
Amazing what the camera shows up, the first shot I took showed a reflection of the camera name on my hand, and can be viewed here!
but I especially liked the lighting in the shot I posted.
Off to do some baking now - will catch up on comments later.
