These Post-It Notes holders start with a 8 1/2"x 3 3/8" piece of cardstock. Fold in half and decorate. I used Anna Griffin double sided cardstock from the Carolina Collection. To keep the note pad attached, I used some additional adhesive on the last piece of paper. I also might mention that I split the pad three ways. I used yellow in this holder, but will be looking for other colors as these are fun to make. The stamp used is from Stampin Up, Punch Bunch stamp set.
