I am ordering custom coasters because we are long overdue for them. I am trying to find a good balance between functionality and style. I know the thirstystone coasters are the most absorbent but none of them really suit my style. my top three options are Slate, leather and wood (bamboo)

I love the wood look the best but it usually doesnt absorb at all. I havent had much experience with leather so I dont know how that holds up and I like slate because it is a somewhat absorbent stone but I have seen reviews about condensation forming under the coaster which would totally defeat the purpose of having it. What coasters do you have and do they work well?
