Ideas for carrying belongings when using a walker or scooter?

Hi all.

I’m a mom with MS that lives in the US. I use a scooter most of the time and - some of the time- a walker.

I’m always scrambling to try to figure out how to carry things when I’m on the walker or scooter. By “things” I mean: my phone, cooked food, papers, my kids stuff, leashed dogs…etc. etc. I’m taking a design class online and I decided to try to design a new system or device that could help folks with MS carry things when they use their scooter/walker…

Anyone have experience with something that works really well for you? Or do you tie stuff to the handles and hope for the best?Is this a problem for anyone else out there (or am I just a poor planner?)

Thanks very much for helping me brainstorm (maybe the creative “hive” mind can solve this problem better than I can). I’m tired of getting tangled in leashes and dropping my breakfast!
