Njuta - 100% cotton towelling, in a striped pattern (one on eBay now, starting price £14.99 if you want to see a picture).
In store at Nottingham, marked down from £22.99 to £5.99 (several sizes, and loads in stock). No doubt at all the other stores as well.
Good quality, nice soft, thick, absorbent fabric, an absolute steal at £5.99.
