I made tops out of acorns I collected this year. After collecting them, I froze and dried them, but I haven't done anything else. They are fixed with glue. I've collected acorns of various shapes and sizes, so please enjoy how they spin. You can also spin them like in the fourth image, so please enjoy. I collected a lot of acorns on my walks this year. If you need any, please contact me. Thank you.
