These are great, and really cute @eveuncovered. I've never done it myself but the guy I learned from, my mentor Jim, told me if you hunt online you can buy expired Instax and Polaroid film. When the photos are developed they do crazy things because the chemicals have either dried or ran in to one another. I'll try digging up a few links and send them to you, but that would be really cool if you like exploring the instant film stuff.
Oh that sounds really interesting! Do send me links if you find some :) And thank you so much, I always appreciate when you take the time to leave a comment.
