Super-Thin Sourdough seed Crackers

This morning my wholewheat dark rye sourdough poppy sesame seed crackers were made so thin they reminded me of papadums. I used a baking mat and my fingers to make them as thin as possible and they baked fast. It was so thin and translucent in spots. I could almost read through it. It was one sheet of cracker. This time no scoring or docking (poking holes with a fork).

I baked them at 450 for a few minutes.
