I made a zipper pouch for Halloween. I was trying a product called Screen Ink Discharge. It's mixed with screen printing ink and bleaches out the dark fabric and replaces it with the color of the ink. I wanted a nice white so I used white ink and I think the skull & cross bones came out nice. I have used soft scrub in the past but I have had some problems with the image not completely bleaching out. The other thing about his Ink Discharge is I can add a color like yellow or pink and it should stand out. I will do some more tests and let you know how that turns out. As for this product as I used it, it worked. I would use it in an area that has ventilation as the label suggests, the stuff stinks. You have to iron the product to make it react, which is fine but it stinks. So be prepared. I would also suggest that you wash the item because it stinks. I did not wash this item and I wish I did. It doesn't smell any more now but it did for about a week. I also added a leather handle on the side as I receives some nice leather scraps from a friend and I thought this was a nice place to use some of that gift. I want to make some more of these as I have some more of the skull & crossbones, as well as the skeleton heads. The red fabric on the inside is a lining that I bought at Scrap in Portland. I bought a used bolt of abut 15 yards for $25 a couple years ago. I have used a lot and still have a lot left.
