I've heard good things about this company. They reknit holes in knits and alter knit garments, all so that the alteration can't be seen. I just bought a NWT St. John with a couple of holes in it and plan to send it to them. It seems like a good link for our Links page. Knit Alterations
They specialize in repairing high end clothing, such as cashmere sweaters and St. John items. It would be very, very useful if you have an expensive cashmere sweater, such as Carruthers, with a moth hole in it. It can be repaired to look like new. It seems like a very valuable service.
