Pattern for 6" X 4 3/4" envelope, to make a larger or smaller size use a
larger or smaller square of paper.

Fold the two side corners into the center so the point of the corner meets the dot in the center of the sheet. Fold the bottom corner up about 1/2" above where the side folds start. Fasten the bottom flap to the side flaps with glue, fold the top flap down in the same manner. The top flap may be sealed with a spot of glue under the point of the flap or with a sticker.
