I have one of the original Chouinard Expedition Sewing Kits, I really like the design. Bought it from Campmor in the early eighties I think. It was tucked away with some of my gear and went un-noticed (lost) for a while, so I put together several minimal sewing kits based on the British Army issued kit. I have them scattered around and have found them very useful. Not something I carry in pocket all the time but if I have a bag of any kind, it has a sewing kit in it.

While this new Patagonia version is rather pricey, I was shocked to see what the originals are going for.
