I really LOVE how it is not just ONE thing...this is great for any hand work person to put on the arm of the sofa/chair! Even on the airplane, bus, train!
I don't use rice though..if it draws moisture it is not a good thing...
I am going to glue to large washers to some mat board for the bottom of the pin cushion for extra weight and stability, then use half corn cob bedding and half walnut shell bedding! with a steel wool pad on top of that to sharpen pins!
