Is there a way to accomplish dying fabric so one color bleeds/fades into another?

What about tie dying? Not sure if that would achieve the look you want? You can do a Google search for how to do it. Sorry if this isn’t exactly what you are looking for.

@Bellatrix No tie dye isn’t quite what I want I want. The top solid black and the bottom solid red but the black to fading into the red mid way down like this Now I know it wont be a clean blend like in the pic but i dont want a straight across blend.

Not tie dye, but a variation on batik. Dye your first color, paint on some wax, let it cool and then crack it where you want the next color to blend. Dye the second color and it will seep into the cracks.
Edit: the effect is something like this but you can adjust the fade as you please with your wax painting and cracking.

@Blueroses hi hunny that is exactly what i am trying to accomplish! but i was reading online that acrylic fabric is extremely hard to dye. that you need a special dye and a chemical mixture for it to actually take to the fabric. oh and i have no clue what your talking about haha. i dont know what batik is, or what you mean by” paint some on wax”. and there wouldnt be a second color, just the black. the fabric is already the other color i want.

OK. Get some RIT dye in black. Test the top of the fabric to see how it will take. RIT will pretty much work on everything and it’s dirt cheap. Get some wax, candle supplies at Michael’s or Hobby Lobby, melt it and use a paint brush to apply it about where you want the fade from black to red. Let it cool and then crack it. Then put the top half of the shawl into the black dye, only up to the wax line. The black will bleed into the cracks and give you the fade.

Fabric chromatography.
Maybe This will be helpful.
Just use the basic steps. Ignore the fact that it can be used as an experiment.

My experience with RIT dye would say that it will bleed and fade all by itself – no special technique needed, just a few washings.

If it were me, I’d take the shawl and fold it in a loose accordion pattern, take a large plastic bag (maybe 2) with no holes then tie the bag tightly over the top half of the folded scarf, perhaps using a rubberband to hold it in place.

This would keep the top half from getting dye on it. I would then patiently dip the bottom half into dye, hold, lift out, dip, hold, lift out, etc, etc but each time I dip the scarf, I’d dip less of the bottom length each time. Dip, hold, lift, on and on—until I was done. That’s what I’d do.

Thank you Everyone! you all were very helpful
