I'm pretty happy with how these turned out!
I just ordered a bulk pack of "thank you from the newlyweds" cards from Amazon and some dried lavender from a local lavender farm ($5 for around 200 stems), and polyester napkins from Tableclothsfactory. I think these will look super cute at my lavender and sage themed wedding at a botanical garden! They'll be sitting on silver charger plates.
Still need to practice my folding skills a bit, haha!
