Recently I went to Little Rock Arkansas for training from California. There I had a delicious burger at a cool little organic restaurant in North Little Rock called "The Root Cafe". Instead of using paper towels, they had a huge stack of cloth napkins. They varied in color, size and material.
You can usually find napkins or kitchen towels really cheap in thrift stores, bed bath & beyond and the dollar store. I will usually build up a basket full and then wash them then line dry them.
The Root Cafe deserves a shout out for that great idea.
