First one is a druggist fold. Imagine a piece of paper divided into a 3x3 grid. Fold the top and bottom up, making sure they overlap (1). Then fold the sides over, making sure they overlap (2). Then take one of the sides and tuck it inside the opening on the other (3). If it'stoo tight, fold one corner over and then try again. Flatten it down, & this will hold it sealed.
Second one requires a square paper. If you don't already have a square, fold one side down and cut off the excess (1), then turn the paper so the point is at the top (2). Fold the top down (3). Then fold each side, and tuck one side into the opening on the other (4).
Third one also requires a square, so fold one side down & cut off the excess (1). Turn the point to the top and fold one side in so the tip almost touches the opposite side (2). Repeat with the other side (3). Then fold the top over and tuck it in the opening (4).
