At Mrs Bow Tie, most of our pocket squares come pre-folded. This means that we fold the fabric into the requested shape and sew it into a cardboard slip to hold its position. The card then neatly slides into the pocket of a jacket or blazer, with the fabric fold showing.
Most of our customers love this timesaving design, which allows them to have the perfectly folded pocket square without anyone knowing they haven’t done it themselves, but many others still prefer to try themselves. If so, you should purchase a handkerchief/unfolded pocket square, which is loose fabric.
