I am just geting into i spy quilts yours is great. I plan on making more.
My DD in her job transports kids. She bought a new car so I made an I SPY quilt for her to put on the back of her seats.
This not only will entertain them but prevent them from leaving shoe prints on the new seats.
IT worked great. On her last transport (an hour ride) All you could hear was...I Spy with my eye an horse...a racecar etc.
She also asked them to find things. They took turns and they were quiet, and it was her first trip without tantrums.
I just put straps on each top end to go around headrest.
just an idea for someone else to do.
