Again, thank you VeggieJess for the inspiration to get this done.
This is what I came up with. I decided that if I've been using a shoe forever then I'd make a long shaped one. Also I used batting (I think that's what it's called ) inside and made a little bag and put pebbles in it then sewed it up. It's kinda wonky, but will do.
Here is an action picture. I really needed this door stop like forever.
