I came across Fresco Towels after I fell in love with them at Anthropologie a couple months ago. Of course they are your standard old terry cloth towel, but they look like vintage Moroccan textiles. They are saturated with color and pattern and really are not fully appreciated until you see them in person. They are the towels that really make a basic, clean white bathroom to the next level.
These fresco towels are sold at Anthropologie
And here are some at Calypso Home
