Print out the rainbow planner sticker sheet. This includes a rainbow color strip you can use for all kinds of cute crafts. Cut out the color strip and trim to the size you'd like.
Using the glue stick, adhere the rainbow paper to the cardstock. Trim to size leaving a small boarder of cardstock around the rainbow color.
Using the marker, draw or write whatever you'd like on the bookmark.
Seal the entire bookmark with packing tape by apply tape on both the front and back. Trim to size. I like to leave a small board of tape around the edges of the bookmark, but you can trim the tape flush to the cardstock if you prefer.
Punch a hole at the top of the bookmark and add twine or ribbon to create a tassel.
