Let's start with some brainstorming.
What is a hole? Does it have to be round? Can it be a slash or a cutting? Does it have to be the same size?
Some ideas to get you started and I am sure you will come up with many more which many of you already have.An opening in or through something
• Think of natural openings
• A crevice in a rock face or wall
• An open space in between things such as trees
• A perforation - think lace or punched holes or lacey paper
• A line of small holes
A deliberate hole
• A buttonhole
• An eyelet
• A keyhole
• A manhole
• A peephole (does it have a cover?)
• A manhole
