Oh, I use mine all the time. Has anyone made them from clothesline and fabric? That is how I make mine and it will absorb anything that drips from your glass or cup.
Just wrap strips of fabric around cotton clothesline rope and sew in a circle with a zigzag stitch. Done in no time! I will have to do a demo on it if anyone is interested.
You can make them as big as you want or as small as you want. These make the best hot pads to set a hot pan or dish on.
I am sure everyone would have hard time finding scrap fabric to use...:)
