I am debating whether it would be worth it to get a special iron just for quilting. I use a Black & Decker for general ironing, and it does fine for my sewing (at least, I think it does- I'm a newbie to quilting, and I have nothing to which to compare it). My question is- is it worth it to get a "special" sewing iron, like a Rowenta (or any other brand you may suggest)? What are the benefits? Thank you!
