THIS IS AN EDIT/RECOLOR. Meaning all I did was edit a pre-existing template to look like kh2 Kairi.
I used one of the various templates from desubunny's gallery to make this. Please check out her page! [link]
I honestly hope this inspires someone with better skills to make a papercraft Kairi template. xD Mine is sorta awful to be perfectly honest. Haha.
Feel free to send me pictures if/when you make it though. :3
