Thank you guys so much! I am really happy with how they turned out! This was seriously the first time I made this recipe since I was in the brownies making Christmas ornaments.
To make the biscuits, I used 1 cup of salt, 1 cup of water and 2 cups of flour (and I had to add a small handful of flour to the batter as well, because it still felt too sticky...) Then I stuck the dough between two pieces of wax paper and rolled it out so I could draw the design onto the dough with a toothpick. I baked them for about an hour and a half (or so) at 250 degrees until they were really hard. After I let them cool down for a bit, I painted them and strung them up on my wall.
