I had to have a quick search online to see what other things there are that are bad luck that I could squeeze into my picture in my lunch break.
I have shoes on the table, two umbrellas open indoors, a ladder that I am sitting under, a black cat (I edited her in so she appears twice) and even a broken mirror by my odd socks.
Behind the scene
I put a real mirror down on the floor and edited in some fake cracks. I took multiple photos so I used one of the pictures where I had my cat walk around before climbing on my lap so I cut her out and pasted her onto the next image.
