Hi I don't post very much but I had to add to this post. In the last day or two someone showed info. about dense black foam called quilting buddies (I think that is the name) for using when FMQ. I have not tried these but I thought that the scrubbing spounge that we buy for pots and pans might work. I had some that I bought at Target some time ago and still had some and got those out and they work just great. One in each hand and you can just zoom along. Try it. Oh yes, the spounges I had were about 1 inch thick.
