Wow, I can't believe the people who aren't enamored with the super slider and the pounce. I use the pounce on regular stencils and it sure does come in handy. Although it does look like a cocaine den when I'm done, but I get the one that irons off. The super slider has saved me when it comes to FM anything on my regular sewing machine.
I guess I'd have to say specialty rules as well would be something I would have to take a second look at, I have so many and don't use half of them, but they're so cool when you see them work.
