I was going to the kitchen to look for a food that had some leading lines, and at that moment my mother happened to be cutting onions. I took a look at how they were sliced and realized I could use them. The focus is on the onion in the front, but if you follow the lines, you’ll see the other onion and the knife. My idea is that the viewer might wonder why the onions look like that, and then they would look back and see the source of the cuts.
