Reading all of the topics in the forum on dyed props, I experimented with stripes and bright colors. I did not place my props in boiling water. I was afraid that the plastic would loose its shape or loose its temper and become weak and flex excessively when under a load. The water was hot, but far from a boil. I soaked for approximately 45 min., then removed the tape (stripes). The dark stripes were created using a black Sharpie.
