I have decided to call these works "The Fenestra Collection" Fenestra is latin for window. Its a term used in zoology as a small natural hole, especially in bone. I thought this fit perfectly! Thank you to everyone else who gave suggestions! They were all great!
* NEED SUGGESTIONS * I will be showing this collection on March 17th! This collection needs a name! I have been calling them the "doorways" or "windows" but would love ideas for a name for the whole collection
