here's how you make your very own magnetic boards from old cookie sheets:
first you need a couple of old cookie sheets and some spray paint
put the pan on a surface you don't mind getting splattered, like a garbage can:
spray till you have a nice even cover
and they will look something like this:
or this
then by the time someone is ready to get out of the pool:
(yes, he's in there with his shoes on. yeah. i know)
they should be dry and you'll be ready to take them inside.
now you need some sticky back velcro, and attach it to the back like thus:
take the backing off the other half of the velcro and stick it where you want it.
i decided the inside of my 'witchy' cupboard was the perfect place.
and there you have it. a simple easy way to make your own magnet board!
