These are quick and easy to make as well. You start with a full sheet of cardstock and cut it to 4 1/4″ x 11″. Then score at 1″ down both long sides. Turn the cardstock so the long edge is along the top of your paper trimmer and score at 1″, 5″, 6″ and 10″.
Fold and burnish your cardstock on each score line. Then hold your cardstock with the long side horizontal and “cut in” on all the lines until you hit the 1″ score line. You will also want to “miter” ONLY the little flaps. . Lastly cut off the two little flaps from one end. On the other end, notch a half circle using a punch or a small circle die. This makes a finger hold for opening the box. (See the photo below.)
