A suit or a duster, a shirt or a skirt ... All deserve to be treated for what they are. They all have different shapes and different fabrics, so they must be ironed differently.
Iron the lining first, then the neck, waistband and pockets (plus any laces and frills). Then move on to the sleeves and finally the back and the front.
Iron the neck first (stretching gently to flatten it out and using the tip of the iron to avoid wrinkling). Then iron the yoke, arranged neatly over the tip of the ironing board. Do the cuffs and sleeves, and finally the front and the back. Iron folds from the reverse side to avoid flattening them.
Iron the lining first. Iron the waist from the reverse side. Then iron the rest.
Iron the pockets and waistbands from the reverse. Turn the right side out, aling the inside leg seams and iron one leg at a time. Cover with a cotton cloth to avoid shining.
Iron the top first. If you have nobody to help you, drape the ironed part over the backs of one or more chairs and move the chairs gradually away from the ironing board as you proceed. Place a step ladder near a window before you start, so that you can hang the curtains up quickly before they get creased again.
Iron the edges and any embroidery from the reverse. Fold in a half first and iron from both sides. Then fold iron again, but avoid ironing the folds. Gradually rotate around tablecloths on the ironing board for a first pass, then fold in half and fold the ends in until they meet in the middle, so that the tablecloths forms a large rectangle. Finally fold the tablecloth as needed to obtain a neat square or rectangular shape.
Starch items first then pin them outside down on the ironing board, inserting the pins at regular intervals to maintain the original shape. Iron while still quite damp. If necessary, iron the edges again after you take the pins out.
