I've been a fan of Wee Gallery for ages, so I was excited to see their collection expand to rubber stamps! My favorite is the safari set of stamps. I don't think you need to be wee to love a giraffe stamped in your notebook.
ps. I went to a friend's baby shower brunch yesterday, and she got these fantastic brass animal hooks as a gift. She's had her eye on these hooks to hang in the navy nursery (with a striped green ceiling) for her soon-to-arrive baby boy. I can't wait to see the nursery in person — such a cute idea!
