Ellie, love that vintage paper!
I also made a baseball themed card. Found the pattern on Pinterest. Once I found my red embroidery floss and some textured white cardstock, the card went together pretty quickly. (The inside reads, "I raised mine!" Am giving a packet of cards to my sister... who has three sons, all are athletes who excelled at different sports, baseball, football and hockey!)
