Ok - I'm the nut who made the homemade curling stones -it was way more fun than we ever imagined for kids and adults !
Here is the link I based the stones on:

Also, Imade a few adjustments including smaller 18 # rocks (vs 42#) because I have to transport them but they worked just fine.
If you are at ALL interested check out the link and just do it !
My son Sam after a great match!
