Do you have a kite chucker? A kid that takes particular joy from making you chase an abandoned kite across a footy oval? I do. Today was a different day though, my kite chasing days may be behind me...
It's an admittedly a low tech solution but super affective non the less! I got a strap with Velcro on the back and put a carabiner on the front. The kite handle clips on so they can still fly it but it's not going anywhere.
My six year old daughter doesn't need to use it but decided hands free flying was super cool so ended up having a blast with it too.
We were using a 'Pocket Kite' that we got from the Scienceworks gift shop for $10. It is very, very, very easy to fly.
