This is such a cool idea! I need to find old rims now.
Love this idea for school field. How many rims did it take to do?
Thanks for the compliments! Have fun making your own! To br honest it is such a long time ago we made this, I can't remember how many wheels and rims we used. A lot! Started with a tiny one in the middle on the very top, maybe it was a 16inch wheel than a row of 24inch, a row of 26..... the second one turned out a bit more egg shaped, but still fun.
