heartburn remedy (also for indigestion): 1 T. Carrier oil, 2 drops peppermint, 2 drops lavendar and 3 drops sandlewood - rub on chest bone. 1 T. Carrier oil, 2 drops peppermint, 2 drops digestzen - rub on belly. I did both since I had both heartburn and indigestion and it was gone in 2 minutes!
Can you see the chunks that make up a pattern here? You could probably do it several ways. This would take kids quite a while to figure out. Wallpaper is a great source of visual patterns that are repeated. It can be rather long repeats or short repeats. But, regardless, it is a bit of trip to figure out.
