I am certainly into my crackle phase. I have tried several crackle pastes and by far the best is by Golden. If you have any desire to crackle anything it definitely works the best. The Ranger crackle in the tiny bottle just isn't worth the cost of that although it does crackle well.
This is not much of a progression for you to see. After I get my new camera (YAY!) I should be able to take some better progression pictures while it's on the easel.
