My understanding of 'dress' cotton is that it is lighter and smoother than quilting cotton. It has a different, softer, drape than quilting cotton and will handle a little differently.
Quilting cotton is manufactured so that the fabric 'grips' when placed right sides together (although some may argue about how well, lol).
I've used it in a 'Warm Wishes' without too much difficulty and have purchased more for bag/purse linings.
