ATK doesn't recommend microfiber. It is not very absorbent and too thick to get into small places like the inside of a glass.
I bought a couple of years ago some very large flour sacks for a craft project. I had one left over and cut it up into three dish towels. I will never go back to commercial ones. They are not real thick, but they sure are soft and are easy to use. They absorb water very well. I could have gotten four towels from that one large one. But I wanted them to be thicker than a single layer would be. So there was just
enough to make sew them into double layers. I cut strips of cloth just a tad smaller than the towel was going to be. That way the middle of the towel could absorb water from large items, yet the edges were thin enough to fit into glasses.
BTW, single layer diapers also make great absorbent (cloths) towels.
