I kind of have a love/hate relationship with magazines. I love the images and the visual inspiration but I'm usually lucky to get 1 idea out of each issue.
I recently came across this AMAZING online magazine specifically for kids packed with gorgeous photos, amazing crafts and projects that the boys can do with little help.
It's called Action Pack
They allow you to download a few freebies (I love the fish trap) and issue 4 - the current issue - has lots of outdoor/nature projects. You should definitely check it out if your boys are like mine and LOVE projects and DIY activities
