As requested elsewhere, here is the cracker recipe I've been using
4 cups flour (i used whole wheat)
1 t baking powder
3/4 lard/shortening (i used coconut oil)
1 1/3 c milk
Mix together well. Roll out very very thin. Place on greased baking sheet. Sprinkle with salt as desired. Bake at 350 degrees for 10-15 minutes until crispy.
Variations:
I've also put some melted butter on the top (similar to a ritz cracker) before sprinkling with salt.
I've been thinking about adding some shredded cheese to the dough for a cheezy cracker, but haven't tried it yet.
Another variation I've been considering is sprinkling ranch dressing mix (can use homemade mix) on the top for ranchy cracker.
