I have nearly enough responses on the poll to publish the results. I want to just try to get one more to hit my minimum sample size. Thank you, everyone who's already responded!
TOP 5 FAVORITE THUMBLINGS
I've found so many that seemed impossible at first! Little Finger was Ditu Migniulellu. Three-Inch was Der Angule. Master Thumb was Nga-Let-Ma, or something like that, anyway. But I still have a list of resources I'm looking for.
This website is based on my research into folklore. Home to the Thumbling Project, collecting different versions of Tom Thumb and Thumbelina from around the world.
