Nearly all cottons and linens should be shrunken before being made up. Probably the most satisfactory way is to place the folded piece of material in a tub of lukewarm water and to allow it to remain in the water for about one hour. The material must be thoroughly wet, even to the innermost fold. The material should then be removed from the water, but not wrung, because wrinkles will appear which will be difficult to press out. The greater the care taken in hanging the material to dry, the easier it is to press later. The material should be hung with the selvage as straight as possible. It should be ironed just before it becomes dry, great care being taken to iron it with the warp and filling threads, or with strokes both parallel to the selvage and at right angles to it. It is most important to keep the warp and filling straight, to prevent difficulty in placing a pattern on the grain of the material.
