I used to be horrified about the amount of paper towels that I went through as a painter. Too many trees! Then one of my students introduced me to blue shop towels. You can get these at local hardware stores. These towels are sturdy and absorbant. If you are using watercolour or watermixable oils, at the end of your session you can quickly rinse the towel out and use it again and again. Even with acrylics, the towels are so much more absorbant than regular ones that I use a lot fewer. Hope you will also go green with blue towels – and thanks for the tip Judy S.
