Make a Flour-paste crackle effect- Spread flour-water mixture over fabric, let dry. Crush to crackle it, then paint fabric. The dried flour mixture acts as a resist. Then washes out. This might work for a "batik" look, too! Use 1 cup flour with cup water
Ombre tie dye - Apply a line of dye along fabric edge. Use a large wet paintbrush to push dye upward on fabric. Continue dipping brush into water and brush along edge of dye, pulling colour upward to create a gradation of the original colour.
