Yes I have a set of those FM quilting discs which I bought about 6 years ago. They were distributed by a different company (Quilt Sew Easy Discs by Heavenly Notions) but look like the same thing. The blue foam is really dense and grips the fabric well allowing the quilter to smooth out any wrinkles and flatten the fabric for quilting thus preventing wrinkles and puckers. I like them as you don't have to wear gloves and they have been helpful to me.
