Fold in 1/2. Unfold. Fold top edge & bottom edge to center crease. Unfold. Fold top left corner & bottom right corner to 1st crease. Fold top & bottom edge back to center.
Fold bottom left corner up to top edge. Fold top right corner to bottom edge. On left side, open slightly to tuck under flap where my finger is. Repeat on right side, tucking where my thumb is.
TURN OVER. Fold bottom up as shown. Fold top down as shown. Let those 2 folds come open. These are flaps u will use to tuck into pockets (pockets are on opposite side). Make 6.
Now u can begin sliding the flaps into pockets. I showed two getting tucked in, it's ur challenge to connect them all. It's really not that hard 😜
