For those who have experience with batiks, should I use these in something that will hold up well to washing, or are batiks mainly for admiring. Having never worked with them before, I'm not sure if I should use them in gifts where I know they will be loved AND used. The colors are amazing and I loved working with them, but am not sure how to use them now. I would appreciate your opinions. :-) Oh, another thing, after prewashing them with a "color catcher," is it necessary to use a a "color catcher" with every wash?
