Baby Shower for cousin

In two months time my cousin will be having a new additions in the family. They plan to baptize the baby when it reaches three months and their parents want a small party and I thought of sweet pea baby shower as the motif of the party, so I told my cousin that I found a website that sells different kinds of party supplies with the said theme from invitation to the tableware. Since it's twins so it will be the perfect motif just like peas in a pod.
