I don't have to convince you guys that an invitation to a party is the first, critical impression of what's to come.  Capture the spirit (get it — spirit?) of the DIY Halloween party with this envelope liner, handmade by you, turning a simple black envelope into something that will have your guests RSVP'ing well in advance.
Kelly at Studio DIY shares the simple envelope how-to.
