Steve Spangler Science. But it was the first time for us, and we enjoyed the results so much I just have to share!
What worked well for us:
1. Use small cups and a rubber band that fits tightly.
2. Experiment with the different sharpie colors. Some bleed more than others. Some leave a more distinct line. (We found that our blue pens didn't bleed much, but the purple and yellow spread quite far)
3. Use a paintbrush to dab on the rubbing alcohol rather than a eye dropper . The color bleeding is easier to control if you use less alcohol. Only use rubbing alcohol that is 70% alcohol or higher.
4. Wait for the alcohol to dry almost completely before you remove the rubber band. If you remove it too soon the colors will bleed beyond the circle.
5. Pay attention to what colors are next to one another. Those colors will mix, and it is too easy to end up with ugly browns if you don't pay attention.
6. Leave lots of white space between colors.
7. Symmetry in the sharpie design makes for a more attractive circle.
8. Flower designs look especially pretty.
9. When you are done with one circle, start the next circle in a very different part of the fabric. If your rubber band cinches a circle that is still wet, it will mess up the design.
Have you tried the sharpie tie dye method yet? What tips could you share? We'll probably be doing this again, and would love to have some new ideas.
