I feel like I cheated a bit on this one, but I'm okay with that. The main thing I want at the end of summer is lots and lots of photos. So what I did was find a Summer Photo Checklist. The one I used is from Simple As That and can be found here. I printed it at 4x6, but it's normally a full sheet size. I probably won't take most of the photos on the list, but I thought it represented what I want for the summer.
I didn't use the technique for the prompt, even though I like the idea. Maybe another time.
The label says: "At the end of the summer... I want to be in the habit of taking photos every day."
