I found this example of a Hand Heart collage where you take photos of your arm at different angles, then put them all together to form a heart. I thought this was cool but i couldn't find an app to make it or a tutorial. So i went onto comic life and used the panels to place each photo in a collage. I just used this example as a guide to mine.
This Is my Final product. It consists of !6 photos in total. If you look closely you can see that only 10 of them use mu arm. the other 6 are just filler photos to make a complete box.
