Tie-dying is definitely one of the best DIY activities ever created. It's fun and can be used in so many ways. Another benefit of tie-dying is that you will always be original, but that is basically a benefit from all DIY's. Tie-dye is special because you can experiment with original prints.
Stuff you need:
Plain white tee
1. Collect fabric beneath the sleeve of the tee.
2. Dye the fabric then remove the neck.
