I decided to combine some of them into this book mark printable. (By clicking on the link you can download a copy.)
I printed the bookmarks on to heavy white card stock.
Big Brother then used two different colors of green ink and his fingers to add leaves to the trees. (Quick clean up note: baby wipes work really well for taking ink off fingertips.)
After he had created the leaves we cut the bookmarks apart, added names and he signed his name on the back. We then ran them through out laminator. (Have I mentioned yet how much I love our little home laminator for this kind of project?) I ran three through at a time using one sheet of laminating film.
When we'd finished laminating we again cut them apart, punched a hole in the top, and added ribbon. We were left with a beautiful finished project. The teachers loved receiving along with a big, giant Big Brother hug.
