Labels, stickers, and envelopes

Labels and stickers are specified by the text on them and the quantity, not by a catalogue brand. Use them for jars, files, or packs. Say if the surface is curved so the proof can note that.

Envelopes are a separate item. Wedding envelopes can follow the invitation style. Office envelopes can be plain or carry a return address. A window, if you need one, is drawn on the proof before any die is assumed.

Letterheads sit with this family of stationery but have their own catalogue item, because a letterhead is not a sticker and not an envelope.
