Care instructions for COTTON and cotton blend fabrics. My advice - wash your fabrics before you create your wonderful project. I don't always follow my own advice as I am anxious to start my quilt, or garment right now, but it is best to pre-wash your cotton fabric. When you wash bright or dark colored clothing for the first time, you probably wash it by itself. Most of us have washed a bright colored garment with white clothing and ended up with the white garment being discolored. Pre-washing allows the excess color pigments to be released (almost all of our fabrics are "color fast", so no problem with color pigments being released in washing, but pre-washing allows your fabric to take it's natural shape prior to making your quilt, garment or decor item made of cotton fabrics. It has been suggested that you wash a sample of the cotton fabric to see if any changes will occur, (but I don't bother as all of the fabric from Beverly's fabric and crafts is of superior quality). If you do test the fabric - cut an exact size and then wash, then measure and you can see if any change to size occurred. We suggest you use a liquid, color free detergent and don't use a fabric softener, bleach or scented detergents for cotton blends or 100% cotton fabrics.
