On my other site, Infarrantly Creative I got a little creative with cereal boxes. I am a big fan of recycling anything and everything I can. Most people toss cereal boxes when the cardboard is primo for art projects, drawing surfaces and POSTCARDS.
So I cut some down and rounded the corners and then added lines for the address on the back. They make the perfect sized note for my preschoolers to send Grandma a note.
