Lost hat on Peckham rye this afternoon 10/10

[mrs f]

I'm utterly gutted to have lost a hat my son's great grandma knitted for him... It's green stripes fairly simple design. I lost it this afternoon between the playground & the zebra crossing by Barry road going via the arboretum at around 4:15. I retraced my steps but couldn't see it but may have missed it or perhaps someone picked it up & put it somewhere???

It's really special to me as my grandma isn't all there with the knitting these days & it's really cute... Clearly my son is less of a fan but I was planning on saving it for siblings so please if anyone sees a green stripy baby hat please let me know

Thanks so much
