01 - Preheat the oven to 325°F and line a baking sheet with parchment paper.
02 - In a large mixing bowl, combine all the seeds, sea salt, and garlic powder. Stir until evenly distributed.
03 - Pour in the water and stir thoroughly to incorporate. Let the mixture rest for 10 minutes until it thickens and the chia and flaxseeds form a gel-like binder.
04 - Transfer the thickened mixture onto the prepared baking sheet. Using a spatula, spread it into a thin, even layer approximately 1/8 inch thick, pressing firmly to compact.
05 - Bake for 30 minutes until the surface is set and beginning to dry out.
06 - Remove from the oven and score the sheet into desired cracker shapes using a knife or pizza cutter. Return to the oven and bake for an additional 10 to 15 minutes until golden brown and crisp throughout.
07 - Allow the crackers to cool completely on the baking sheet, then break them apart along the scored lines.
