One thing that has been super fun about helping out with my little sister's wedding... discovering the world of calligraphy. Oh my. What a world of prettiness out there! A couple of favorites are Laura Condouris (trial by cupcakes is her etsy shop), and the lovely Anna Bond of Rifle Paper Co.
I've been practicing pen strokes for my very amateur effort. There is something so old-fashioned and satisfying about sitting down with a little jar of ink and a calligraphy pen. I would love to really learn how to do this properly.
