From our friends at DesignSponge:
When I throw a party, I go hard. Really hard. Like, paper invitations, cheese plates, and crudités kind of hard. Sometimes there's even a theme--I don't mess around. This is why, when I stumbled upon Yellow Owl Workshop's booth at this year's National Stationery Show, I fell head-over-heels for their new paper party kits. These little all-in-ones have everything: invites, envelopes, favor bags, and stickers that double as seals for the envelopes and favor bags.
