If you have more than one person using a bathroom in your house, it is all too easy for their towels to become crisscrossed. Wondering which towel is who’s is always slightly unsettling and inconvenient. Unsettling because nobody wants to choose the wrong one and have the other person think they have been left with the wrong one too, and inconvenient if you find a replacement for ultimately someone will need to wash all those towels.
A quick fix for this is to sew on colourful loops on one edge of each towel. Designate all parties involved a colour, and things are all settled. This will also make hanging the towels from hooks easier, and will confirm that they remain hanging and not in a puddle on the floor. I imagine it goes without saying, but it is preferential that you consider the colour of the towels prior to deciding on the loop colour. This can be an attractive addition, when done with coordination in mind, or an eye sore if you make no effort on this point.
Having your lovely towels hanging in a bathroom is also of a decorating benefit. They will bring in texture, and colour against something otherwise mundane, or monotone as a door, or tile. Thus, even if you do not have an issue with towels becoming confused, these loops are beneficial.
