Here's a link to my weekend project.....sooo easy! Best part...it occupied my 3 under 2 DCKs most of the day yesterday (& was a fantastic backdrop for my felt stories!!) I happened to get all of my materials for free (leftover from a house project) & was ecstatic to finally have a use for the oodles of magnets I have horded/inherited over the years....
