Order from Horder is well stocked with all the usual office-supply stuff - clips, pens, pads. But where the store really shines is in the fun papers and invitations.
Crane is well-featured but not the only custom-paper possibility. Literally binder after binder presents the options for virtually any invitation, announcement or stationery one could possibly dream of. For those not in the market for custom work, there are plenty of boxed options, too, with lovely linings and envelopes and even engraved highlights.
The only hard part about patronizing Horder is choosing from so many beautiful options.
