James, I, too found the "pouncewheel with a sponge" to be something I think could be very useful. I checked micro-mark, amazon, hobby lobby, and Michaels and found nothing. I would like to know how to get one.
In fact, I wish FSM would do a better job of listing the real name of products and how to get them. I remember they did a list at the end of the article in the distant pass with that type of information.
I know they don't want to give away free advertising, but it is annoying to read a article about a great technique and be unable to figure out what products were used and how to get them. I seem to be noticing this more often lately.
