|A presscloth is a good alternative to steam when you want to control the amount of moisture and try to shape or finish your garment nicely. Steam can sometimes be too much. With a press cloth you can dampen, dry press, and allow to cool before moving on to a new area.
There are purchase press cloths available but its simple to make your own. White or natural fabric is best, cotton or linen.
If you use muslin or even a new linen hankie be sure to wash first to remove any sizing. The stiff sizing will goo up your pressing. A really old soft mens linen hankie is the best!
Here's the instructions I was given for damp cloth pressing:
Keep a small bowl near the ironing board and dip your cloth in and squeeze it almost dry so its just sorta damp.
Don't use steam setting on your iron. Let the damp cloth provide the moisture.
Heat doesn't have to be high, you can 'caramelize' your fabric with the heat too high. Make a test.
Press thru the cloth onto the inside of the garment, not the outside fabric if possible.
You can also use your damp cloth to stroke the area to be pressed to moisten it a bit, then apply iron to that area without the cloth. This works well with tiny areas that you need to see clearly what you're doing.
'Underpressing' or pressing your seams as you work, is a great way to get a professional looking finish. Don't save up all your ironing until the end! A presscloth can be a great help.
