Batik treatments?
I recently aquired a batch of batik fabrics from someone cleaning out a stash. I've only used a few batiks once in a bargello where everything was blue - green, so have little experience working with them. I want to use a couple of them in charity baby blankets I'm making which will be largely white so I am nervous about color bleed. Given that I have no info about the origin of these fabrics (home dyed, store bought?) what should I do to ensure that the colors are set before I cut & use them? Is just a pre-wash enough with batiks? Thanks everyone! Shannon
