I have several cashmere sweaters, and find the Cashmere shop in Masham a good place to look for more. They also do repairs and so forth and are good about checking the problem and giving you a good idea of the price. You can also see them on line and they show both the cashmere and also lovely silk scarves too. I have always found the staff most helpful and not at all pushy, so would definitely suggest that that is a good place to start. I have always washed my cashmere by hand and with care, and it has paid off. One of my very old ones started to get a couple of holes under the arms, but it was brilliant to wrap in plastic bag and put at the bottom of rucksac, so that if you were up on the tops and the weather turned cold or windy, they were still marvellous to war and keep warm. They are worth taking care off and give me a lot of comfort and warmth.
