Metal/Wood
This prompt reminds me of the old game paper/scissors/stone.  Scissors cut paper, paper covers stone, stone breaks Scissors.

I inadvertently left the above  picture out of my Thanksgiving post, and now I’m glad I did.  I love the movement and texture in the potatoes, and the spoon–with the stainless bowl and stem and the wooden handle––is my favorite.  It belongs to a set Bob brought into our marriage.  Most of the pieces have been broken or lost, but these big serving spoons come in handy every time company comes!

This large wooden heart shown in the Maestros del Arte Feria is covered in metal milagros.

This life-sized hand also covered in milagros came home with me!

The wooden barn is to protect the buffalo in a park in Sheridan, Wyoming from harsh Wyoming winters. The metal mesh fence is to protect park visitors from the buffalo!

The wood married to metal of the scaffold is echoed in the wooden handle and iron head of the hammer.
