Square invitations for those times you want to be anything but Square. Our blank square invitations need matching envelopes that are 1/2" larger than the invitation. A 5 inch square invitation will fit nicely in our 5.5" Square envelopes. If you don't see a size or color that you are looking for, be sure to contact us. Since we make these square folded invitations in our midwest warehouse, we can complete a custom order in 2-3 day.
