Hello! Being a graphic designer, I am planning on designing everything (invitations, Save the Dates, programs, etc.) including signage for the ceremony and reception. But I really have no idea what size to make them and where to order custom signs. What's the typical size for a sign to put on an easel, what would the signs be made out of, and where is the cheapest place to order them (our budget is very low and mostly DIY, so the cheaper the better)? Thank you!
