Hmm. I tuck the corners in first, deep into the pocket. Then I bend the apex of the square (approximately the center of it, if it were laid flat) around and stuff it in next. I adjust and push the whole square further in until only the top of the bend peeks out. I like very little to show--the pictures I posted were taken from an above angle, so the squares are more exposed in them. The folds wind up being curved and generally echo the top curvature of the poof. I hate vertical folds.
