Sprinkle additional bran on the board before rolling out if desired.
Cut with a pizza cutter into 1½-inch crackers.
Lift with a pancake turner and put on cookie sheet.
Prick and bake at 375-degrees until toasty brown, about 12 minutes.
Turn off oven and put crackers back in the oven and let them dry out slowly (in a gas oven with a pilot light, check for crispiness after about 30 minutes)
