Make sure your home dec fabrics are washable and the pattern you are using does n ot have small pieces. They will for the most aprt be a little heavier than your cotton fabrics so you need to take that into consideration when picking out a pattern. You also want to be sure that the fabs are not "coated" with any kind of chems for wet/dry or have a plastic/rubber backing...not ironable! These will really mess up your iron plate!
If you are going for the brocades or the embroideries, etc. that will be beautiful, just remember that it will be heavier.
