Block Fusing
The first step in sewing your Marais is optional: Interfacing.
You may opt to skip the interfacing altogether for relaxed cuffs & collars, though we do recommend interfacing for the following pieces: one collar, one collar stand and half of each cuff piece.
Place the glue side down on the wrong side of the fabric. Cover with a lightweight pressing cloth - this can be some fabric lawn.
Try not to drag your iron along, as it can crumple or misshape the interfaced fabric piece.
