Birthday

Midnight

Near-black with gold type

Made for an evening rather than an afternoon. The type is gold on almost-black, so it wants a dark room.

Your names, your date and your venue go on in a few minutes. No design skills, and nothing to install for the people you send it to.

Charged once, when you publish. Building it and seeing the whole invitation is free, and you can change the design afterwards without paying again.
