Label microfibre cloths

Thanks to a friend, I bought 20 microfibre cloths for a great special price. The problem is, they are all light blue. Since I have a habit of having multicolored sheets where each color is assigned to a particular usage, I had a problem here.

So I took 2 towels. With the 1st cloth I have written on the label where the washing instructions are written on it with a ballpoint pen, for what I want to use it. On the second cloth, I have written on it with a waterproof pen the use. Then the two cloths washed with my coloreds at 60 degrees.

Result: On both towels is still to read what they are to be used!
