March 20th - Update: This is the final version of what I decided to go with. I'm making a series of the floral graphics and tying it together with the background color and pattern of the cards.
So I got the sketch into the computer. Here is how it turned out. I scanned it, turned it into a vector, then digitally colored it. I think I'll pair it with an orange envelope. The coordinating journal and notepad will be cute, too, with blue text.
