I love the designs, and they definitely prevented soaked clothes - but out of the 5 I bought 2 had to be replaced immediately because the press-stud came off when I took them off DS2. I got replacements straight away, but one of the replacements immediately did the same thing.
A friend of mine makes some fabulous ones for £4 each, she has an online etsy shop - mamafactured. They are double sided and she has some fab fabrics. I used them with my DD and know lots of people who love them. They are much nicer quality than the ones from M&S
Towel, £2 in supermarket. 4 fat quarters for £5 in fabricland. Sew on velcro £1.50 per metre. Measure round neck + 6", use this as the diagonal of a square. Cut square from both fabrics, cut in half along diagonal. Pin one cotton to one towelling, right sides out, and hem. Sew velcro on to corners. Repeat with other triangles. Wash 2-3 times before use for absorbency and fluffing
