the nubby fabric is called Minky! Thanks to SewGreen at http://sewgreenm.blogspot.com for letting me know the name. It was probably printed on the end of the bolt it was cut from, but I was too excited to look. I have 2 more to make, for an after Christmas get-together.
I also made drink sleeves for my BFF Nancy. She was thrilled and wants more, some larger for soda glasses. They were fun and quick to make.
Here's another view. They take very little fabric, just a few inches really. I have lots of scraps that will come in handy for this.
