I didn't come up with this idea. But thank you to whoever is the original designer because many of us in the crafting world make this wonderful gift, now.
Base: 7 3/8" x 3 1/4"
Pattern Paper: 3" x 2 7/8"
Score at: 3 1/8", 3 1/2", 3 7/8"
Cut 2 slits about 3/4"-1" apart in the middle when the scored section is folded. This will make the pen holder. The 3 1/8" side will be the front of the holder. Use tacky tape or a strong adhesive, put it where the back of the pen holder will be. Fold out the pen holder first. Then put tacky tape or a strong adhesive on the back of the post-it note holder. Put it in the holder then decorate the outside.
