Lost light blue quilt with white stars and moons pattern at Riverside Park playground.

I lost my light blue quilt while hanging out with my kids at the playground in Riverside Park, Western IL. It has a unique pattern of white stars and moons. I was there on Saturday afternoon, and I didn't realize it was missing until I got home. If anyone has seen it or found it, I'd really appreciate it if you could let me know. It holds sentimental value for me.
