I love the Crane note cards. Crane produces amazing stationery that feels awesome! I think they make the best paper products. It can be a little pricey, well it can actually get VERY expensive. However you can get plain cards for not too bad. I love the single flat cards (not foldovers) and you can get 20 cards and envelopes for less than $20. It's pricey but the quality is awesome and I use to thank colleagues in my field, so it's a good investment. The notecards very thick.
