You don’t need a clip to seal an opened bag of chips, and a pack of cookies is no different if you follow CrazyRussianHacker’s simple folding method demonstrated in the video above. It’s best seen than read about, but here’s a short description if you can’t be bothered to hit Play.
Place the pack on a table and flatten the open end, pushing out all the air by running your fingers till you come to the top of the cookies. Fold the flattened open end to one side—this will cause two edges to stick out at the point of the fold. Fold these edges inwards to create a pocket. Then, fold the flattened open end backwards and tuck it under the pocket.
It’s much, much easier than how I am making it sound here. Seriously, watch the video.
