moda bella solids are nice- quilting cottons---they soften with laundering, time & use---they may have some sizing on them when you recieve them- simply wash & dry them- with detergent- fabric softener if you are one to use it- then i generally take them out of the dryer before they are too dry- iron if needed- starch if desired- they are fabrics made for quilts- not stiff...or tablecloth linens.
