I'm struggling with what is the right moment to pour and last time I waited too long. :x So I got a goopy looking surface but when I turn the slab over to cut it, it will have a smooth top. But does it look really amateur to have the bottoms of the bars uneven? I tried to take a clean sponge (one I designated for soap only) to it and at that point it had hardened too much to dab at. Oh, well, at least the tops will be pretty if the freezer paper doesn't turn against me and stick to it!
