I've never done it on quilt fabric, but have often done it on 100% cotton tee shirts. I get inexpensive tees and it's a hit for the kids to do at the cottage. One thing we do is lightly color the whole background area with different colors. Spray heavily with alcohol, then cover with bunched up plastic wrap and let it dry. It gives a marbleized background. Then draw your design and spray. If you are not artistic, you can put a line drawing, like a coloring book page under the fabric. You can just color in the lines. You can control the amount of bleed by the amount of alcohol sprayed. You can let it dry and reapply more color as many times as you want. when completed, I use a dry iron and a press cloth over & under the fabric. You loose a small amount of color when you launder (cold), but it stays amazingly well.
