Hi, Different fiber papers
Different fiber papers have different textures and this is probably what you are encountering. Bullseye makes a paper, called Thin Fire, which is VERY smooth and the only thing is you have to be SURE to wear your mask when you vacume off the used paper after opening your kiln (with a HEPA vacume) as it’s extremely toxic. But this is true of ANY used fiber paper.
Hope that helps,
