If it's a good idea, go ahead and do it. It is much easier to apologize than it is to get permission.

I suggested this a couple-three years ago, thinking of getting the embroidered labels and sewing them on the towels. This was much easier, as I haven't operated a sewing machine for more than half-a-century.
The labels came from a company in England, about a two-week turnaround. Towels can be had just about anywhere. These came to about a dollar and thirty cents each. Probably cut that in half by bulkier purchases.
If you don't like it, I apologize. There are about forty-five left, fewer blue ones than green and yellow.
